CVE-2026-32139
UNKNOWNDataease is an open source data visualization analysis tool. In DataEase 2.10.19 and earlier, the static resource upload interface allows SVG uploads. However, backend validation only checks whether the XML is parseable and whether the root node is svg. It does not sanitize active content such as onload/onerror event handlers or script-capable attributes. As a result, an attacker can upload a malicious SVG and then trigger script execution in a browser by visiting the exposed static resource URL, forming a full stored XSS exploitation chain. This vulnerability is fixed in 2.10.20.
CVE-2026-31873
UNKNOWNUnhead is a document head and template manager. Prior to 2.1.11, The link.href check in makeTagSafe (safe.ts) uses String.includes(), which is case-sensitive. Browsers treat URI schemes case-insensitively. DATA:text/css,... is the same as data:text/css,... to the browser, but 'DATA:...'.includes('data:') returns false. An attacker can inject arbitrary CSS for UI redressing or data exfiltration via CSS attribute selectors with background-image callbacks. This vulnerability is fixed in 2.1.11.
CVE-2026-31860
UNKNOWNUnhead is a document head and template manager. Prior to 2.1.11, useHeadSafe() can be bypassed to inject arbitrary HTML attributes, including event handlers, into SSR-rendered <head> tags. This is the composable that Nuxt docs recommend for safely handling user-generated content. The acceptDataAttrs function (safe.ts, line 16-20) allows any property key starting with data- through to the final HTML. It only checks the prefix, not whether the key contains spaces or other characters that break HTML attribute parsing. This vulnerability is fixed in 2.1.11.
CVE-2026-25529
UNKNOWNPostal is an open source SMTP server. Postal versions less than 3.3.5 had a HTML injection vulnerability that allowed unescaped data to be included in the admin interface. The primary way for unescaped data to be added is via the API's "send/raw" method. This could allow arbitrary HTML to be injected in to the page which may modify the page in a misleading way or allow for unauthorised javascript to be executed. Fixed in 3.3.5 and higher.
CVE-2026-2987
MEDIUMThe Simple Ajax Chat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'c' parameter in versions up to, and including, 20260217 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
CVE-2026-2514
UNKNOWNIn Progress Flowmon ADS versions prior to 12.5.5 and 13.0.3, a vulnerability exists whereby an adversary with access to Flowmon monitoring ports may craft malicious network data that, when processed by Flowmon ADS and viewed by an authenticated user, could result in unintended actions being executed in the user's browser context.
CVE-2026-2513
UNKNOWNA vulnerability exists in Progress Flowmon ADS versions prior to 12.5.5 and 13.0.3, whereby an administrator who clicks a malicious link provided by an attacker may inadvertently trigger unintended actions within their authenticated web session.

CVE-2026-32117
UNKNOWNThe grafanacubism-panel plugin allows use of cubism.js in Grafana. In 0.1.2 and earlier, the panel's zoom-link handler passes a dashboard-editor-supplied URL directly to window.location.assign() / window.open() with no scheme validation. An attacker with dashboard Editor privileges can set the link to a javascript: URI; when any Viewer drag-zooms on the panel, the payload executes in the Grafana origin.
CVE-2026-32125
UNKNOWNOpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, track/item names from the Track Anything feature are stored from user input (POST) and later rendered in Dygraph charts (titles/labels) using innerHTML or equivalent without escaping. A user who can create or edit Track Anything items can inject script that runs when any user views the corresponding graph. This vulnerability is fixed in 8.0.0.1.
CVE-2026-32124
UNKNOWNOpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, the dynamic code picker AJAX endpoint returns code descriptions (code_text) that are rendered in the front end (e.g. DataTables) without HTML escaping. If an administrator (or user with code management rights) creates or edits a code with a malicious description containing script, that script runs in the browser of every user who uses the picker. This vulnerability is fixed in 8.0.0.1.
CVE-2026-32121
UNKNOWNOpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, Stored XSS in prescription CSS/HTML print view via patient demographics. That finding involves server-side rendering of patient names via raw PHP echo. This finding involves client-side DOM-based rendering via jQuery .html() in a completely different component (portal/sign/assets/signer_api.js). The two share the same root cause (unsanitized patient names in patient_data), but they have different sinks, different affected components, different trigger actions, and require independent fixes. This vulnerability is fixed in 8.0.0.1.
CVE-2026-32118
UNKNOWNOpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, stored cross-site scripting (XSS) in the Graphical Pain Map ("clickmap") form allows any authenticated clinician to inject arbitrary JavaScript that executes in the browser of every subsequent user who views the affected encounter form. Because session cookies are not marked HttpOnly, this enables full session hijacking of other users, including administrators. This vulnerability is fixed in 8.0.0.1.
CVE-2026-32112
UNKNOWNha-mcp is a Home Assistant MCP Server. Prior to 7.0.0, the ha-mcp OAuth consent form renders user-controlled parameters via Python f-strings with no HTML escaping. An attacker who can reach the OAuth endpoint and convince the server operator to follow a crafted authorization URL could execute JavaScript in the operator's browser. This affects only users running the beta OAuth mode (ha-mcp-oauth), which is not part of the standard setup and requires explicit configuration. This vulnerability is fixed in 7.0.0.
CVE-2026-32109
UNKNOWNCopyparty is a portable file server. Prior to 1.20.12, if an attacker has been given both read- and write-permissions to the server, they can upload a malicious file with the filename .prologue.html and then craft a link to potentially execute arbitrary JavaScript in the victim's context. Note that it is intended behavior that the JavaScript would execute if the target clicks a link to the HTML file itself; "https://example.com/foo/.prologue.html". The vulnerability is that "https://example.com/foo/?b" would also evaluate the file, making the behavior unexpected. There are existing preventative measures (strict SameSite cookies) which makes it harder to leverage this vulnerability in an attack; in order to gain control of the target's authenticated session, the link must be clicked from a page served by the server itself -- most likely by editing an existing resource, which would require additional access permissions. Finally, for this attack to be successful, the attacker's target must click the specific crafted link given by the attacker. This vulnerability is not activated by normally browsing the web-UI on the server. This vulnerability is fixed in 1.20.12.
CVE-2026-3951
MEDIUMA security flaw has been discovered in LockerProject Locker 0.0.0/0.0.1/0.1.0. Affected is the function authIsAwesome of the file source-code/Locker-master/Ops/registry.js of the component Error Response Handler. The manipulation of the argument ID results in cross site scripting. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-32095
UNKNOWNPlunk is an open-source email platform built on top of AWS SES. Prior to 0.7.1, Plunk's image upload endpoint accepted SVG files, which browsers treat as active documents capable of executing embedded JavaScript, creating a stored XSS vulnerability. This vulnerability is fixed in 0.7.1.
CVE-2026-31879
UNKNOWNFrappe is a full-stack web application framework. Prior to 14.100.2, 15.101.0, and 16.10.0, due to a lack of validation and improper permission checks, users could modify other user's private workspaces. Specially crafted requests could lead to stored XSS here. This vulnerability is fixed in 14.100.2, 15.101.0, and 16.10.0.
CVE-2026-31876
UNKNOWNNotesnook is a note-taking app focused on user privacy & ease of use. Prior to 3.3.9, a Stored Cross-Site Scripting (XSS) vulnerability existed in Notesnook's editor embed component when rendering Twitter/X embed URLs. The tweetToEmbed() function in component.tsx interpolated the user-supplied URL directly into an HTML string without escaping, which was then assigned to the srcdoc attribute of an <iframe>. This vulnerability is fixed in 3.3.9.
CVE-2026-31868
UNKNOWNParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.4 and 8.6.30, an attacker can upload a file with a file extension or content type that is not blocked by the default configuration of the Parse Server fileUpload.fileExtensions option. The file can contain malicious code, for example JavaScript in an SVG or XHTML file. When the file is accessed via its URL, the browser renders the file and executes the malicious code in the context of the Parse Server domain. This is a stored Cross-Site Scripting (XSS) vulnerability that can be exploited to steal session tokens, redirect users, or perform actions on behalf of other users. Affected file extensions and content types include .svgz, .xht, .xml, .xsl, .xslt, and content types application/xhtml+xml and application/xslt+xml for extensionless uploads. Uploading of .html, .htm, .shtml, .xhtml, and .svg files was already blocked. This vulnerability is fixed in 9.6.0-alpha.4 and 8.6.30.
CVE-2026-31859
UNKNOWNCraft is a content management system (CMS). The fix for CVE-2025-35939 in craftcms/cms introduced a strip_tags() call in src/web/User.php to sanitize return URLs before they are stored in the session. However, strip_tags() only removes HTML tags (angle brackets) -- it does not inspect or filter URL schemes. Payloads like javascript:alert(document.cookie) contain no HTML tags and pass through strip_tags() completely unmodified, enabling reflected XSS when the return URL is rendered in an href attribute. This vulnerability is fixed in 5.9.7 and 4.17.3.
CVE-2026-30235
UNKNOWNOpenProject is an open-source, web-based project management software. Prior to 17.2.0, this vulnerability occurs due to improper validation of OpenProject’s Markdown rendering, specifically in the hyperlink handling. This allows an attacker to inject malicious hyperlink payloads that perform DOM clobbering. DOM clobbering can crash or blank the entire page by overwriting native DOM functions with HTML elements, causing critical JavaScript calls to throw runtime errors during application initialization and halt further execution. This vulnerability is fixed in 17.2.0.
CVE-2026-20162
MEDIUMIn Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.9, and 9.3.9, and Splunk Cloud Platform versions below 10.2.2510.4, 10.1.2507.15, 10.0.2503.11, and 9.3.2411.123, a low-privileged user who does not hold the "admin" or "power" Splunk roles could craft a malicious payload when creating a View (Settings - User Interface - Views) at the `/manager/launcher/data/ui/views/_new` endpoint leading to a Stored Cross-Site Scripting (XSS) through a path traversal vulnerability. This could result in execution of unauthorized JavaScript code in the browser of a user. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
CVE-2026-20117
MEDIUMA vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
CVE-2026-20116
MEDIUMA vulnerability in the web-based management interface of Cisco Finesse, Cisco Packaged Contact Center Enterprise (Packaged CCE), Cisco Unified Contact Center Enterprise (Unified CCE), Cisco Unified Contact Center Express (Unified CCX), and Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
CVE-2026-1090
UNKNOWNGitLab has remediated an issue in GitLab CE/EE affecting all versions from 10.6 before 18.7.6, 18.8 before 18.8.6, and 18.9 before 18.9.2 that could have allowed an authenticated user, when the `markdown_placeholders` feature flag was enabled, to inject JavaScript in a browser due to improper sanitization of placeholder content in markdown processing.
CVE-2026-3946
LOWA vulnerability was detected in PHPEMS 11.0. The affected element is an unknown function of the file /index.php?ask=app-ask. Performing a manipulation of the argument askcontent results in cross site scripting. The attack is possible to be carried out remotely. The exploit is now public and may be used.
CVE-2026-3178
HIGHThe Name Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name_directory_name' parameter in all versions up to, and including, 1.32.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability was partially patched in versions 1.30.3 and 1.32.1.
CVE-2026-3492
MEDIUMThe Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.9.28.1. This is due to a compound failure involving missing authorization on the `create_from_template` AJAX endpoint (allowing any authenticated user to create forms), insufficient input sanitization (`sanitize_text_field()` preserves single quotes), and missing output escaping when the form title is rendered in the Form Switcher dropdown (`title` attribute constructed without `esc_attr()`, and JavaScript `saferHtml` utility only escapes `&`, `<`, `>` but not quotes). This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary JavaScript that executes when an Administrator searches in the Form Switcher dropdown in the Form Editor.
CVE-2026-3231
HIGHThe Checkout Field Editor (Checkout Manager) for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom radio and checkboxgroup field values submitted through the WooCommerce Block Checkout Store API in all versions up to, and including, 2.1.7. This is due to the `prepare_single_field_data()` method in `class-thwcfd-block-order-data.php` first escaping values with `esc_html()` then immediately reversing the escaping with `html_entity_decode()` for radio and checkboxgroup field types, combined with a permissive `wp_kses()` allowlist in `get_allowed_html()` that explicitly permits the `<select>` element with the `onchange` event handler attribute. This makes it possible for unauthenticated attackers to inject arbitrary web scripts via the Store API checkout endpoint that execute when an administrator views the order details page.
CVE-2026-1454
HIGHThe Responsive Contact Form Builder & Lead Generation Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.0.1 via form field submissions. This is due to insufficient input sanitization in the lfb_lead_sanitize() function which omits certain field types from its sanitization whitelist, combined with an overly permissive wp_kses() filter at output time that allows onclick attributes on anchor tags. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator views the lead entries in the WordPress dashboard.
CVE-2026-3825
UNKNOWNIFTOP developed by WellChoose has a Reflected Cross-site Scripting vulnerability, allowing authenticated remote attackers to execute arbitrary JavaScript codes in user's browser through phishing attacks.
CVE-2026-3534
MEDIUMThe Astra theme for WordPress is vulnerable to Stored Cross-Site Scripting via the `ast-page-background-meta` and `ast-content-background-meta` post meta fields in all versions up to, and including, 4.12.3. This is due to insufficient input sanitization on meta registration and missing output escaping in the `astra_get_responsive_background_obj()` function for four CSS-context sub-properties (`background-color`, `background-image`, `overlay-color`, `overlay-gradient`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
CVE-2026-3884
UNKNOWNVersions of the package spin.js before 3.0.0 are vulnerable to Cross-site Scripting (XSS) via the spin() function that allows a creation of more than 1 alert for each 'target' element. An attacker would need to set an arbitrary key-value pair on Object.prototype through a crafted URL achieving a prototype pollution first, before being able to execute arbitrary JavaScript in the context of the user's browser.
CVE-2026-2707
MEDIUMThe weForms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the REST API entry submission endpoint in all versions up to, and including, 1.6.27. This is due to inconsistent input sanitization between the frontend AJAX handler and the REST API endpoint. When entries are submitted via the REST API (`/wp-json/weforms/v1/forms/{id}/entries/`), the `prepare_entry()` method in `class-abstract-fields.php` receives the WP_REST_Request object as `$args`, bypassing the `weforms_clean()` fallback that sanitizes `$_POST` data for frontend submissions. The base field handler only applies `trim()` to the value. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts into form entry hidden field values via the REST API that execute when an administrator views the form entries page, where data is rendered using a Vue.js `v-html` directive without escaping.
CVE-2026-2466
UNKNOWNThe DukaPress WordPress plugin through 3.2.4 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin.
CVE-2026-2358
MEDIUMThe WP ULike plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `[wp_ulike_likers_box]` shortcode `template` attribute in all versions up to, and including, 5.0.1. This is due to the use of `html_entity_decode()` on shortcode attributes without subsequent output sanitization, which effectively bypasses WordPress's `wp_kses_post()` content filtering. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The post must have at least one like for the XSS to render.
CVE-2026-21361
HIGHAdobe Commerce versions 2.4.9-alpha3, 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, 2.4.4-p16 and earlier are affected by a stored Cross-Site Scripting (XSS) vvulnerability that could be abused by a high-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality, and integrity impact to high. Exploitation of this issue requires user interaction in that a victim must browse to the page containing the vulnerable field.
