Backstage is an open framework for building developer portals. Prior to version 1.14.3, this is a configuration bypass vulnerability that enables arbitrary code execution. The @backstage/plugin-techdocs-node package uses an allowlist to filter dangerous MkDocs configuration keys during the documentation build process. A gap in this allowlist allows attackers to craft an mkdocs.yml that causes arbitrary Python code execution, completely bypassing TechDocs' security controls. This issue has been patched in version 1.14.3.

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.0.13, the /api/v1/attachments/:chatflowId/:chatId endpoint is listed in WHITELIST_URLS, allowing unauthenticated access to the file upload API. While the server validates uploads based on the MIME types defined in chatbotConfig.fullFileUpload.allowedUploadFileTypes, it implicitly trusts the client-provided Content-Type header (file.mimetype) without verifying the file's actual content (magic bytes) or extension (file.originalname). Consequently, an attacker can bypass this restriction by spoofing the Content-Type as a permitted type (e.g., application/pdf) while uploading malicious scripts or arbitrary files. Once uploaded via addArrayFilesToStorage, these files persist in backend storage (S3, GCS, or local disk). This vulnerability serves as a critical entry point that, when chained with other features like static hosting or file retrieval, can lead to Stored XSS, malicious file hosting, or Remote Code Execution (RCE). This issue has been patched in version 3.0.13.

EdTv 2 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the 'id' parameter. Attackers can send GET requests to the admin/edit_source endpoint with crafted SQL UNION statements to extract database information including schema names, user credentials, and version details.

Precurio Intranet Portal 2.0 contains a cross-site request forgery vulnerability that allows unauthenticated attackers to create administrative user accounts by submitting crafted POST requests. Attackers can forge requests to the /public/admin/user/submitnew endpoint with user creation parameters to add new admin accounts without requiring CSRF tokens or user interaction.

2-Plan Team 1.0.4 contains an arbitrary file upload vulnerability that allows authenticated attackers to upload executable PHP files by sending multipart form data to managefile.php. Attackers can upload PHP files through the userfile1 parameter with action=upload, which are stored in the files directory and executed by the web server for remote code execution.

Natro Macro is an open-source Bee Swarm Simulator macro written in AutoHotkey. Prior to version 1.1.0, anyone with Discord Remote Control set up in a non-private channel gives access to any user with the permission to send message in said channel access to do anything on their computer. This includes keyboard and mouse inputs and full file access. This issue has been patched in version 1.1.0.

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to version 4.8.4, the application allows uploading files (project logos) without validating the file type or content. It trusts the extension provided by the user. These files are saved to the uploads/ directory and served statically. An attacker can upload an HTML file containing malicious JavaScript. Since authentication tokens are likely stored in localStorage (as they are returned in the API body), this XSS can lead to account takeover. This issue has been patched in version 4.8.4.

Chamilo is a learning management system. Prior to version 1.11.34, Chamilo LMS is affected by an authenticated remote code execution vulnerability caused by improper validation of uploaded files. The application relies solely on MIME-type verification when handling file uploads and does not adequately validate file extensions or enforce safe server-side storage restrictions. As a result, an authenticated low-privileged user can upload a crafted file containing executable code and subsequently execute arbitrary commands on the server. This issue has been patched in version 1.11.34.

WWBN AVideo is an open source video platform. Prior to version 24.0, an authenticated Remote Code Execution (RCE) vulnerability was identified in AVideo related to the plugin upload/import functionality. The issue allowed an authenticated administrator to upload a specially crafted ZIP archive containing executable server-side files. Due to insufficient validation of extracted file contents, the archive was extracted directly into a web-accessible plugin directory, allowing arbitrary PHP code execution. This issue has been patched in version 24.0.

The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.

The Applications component of Nokia IMPACT version through 19.11.2.10-20210118042150283 allows an authenticated user to arbitrarily upload server-side executable files via the /ui/rest-proxy/application fileupload parameter. This can occur during the adding of a new application, or during the editing of an existing one.

The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.0.0.3 via the download_url() function. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. Additionally, the plugin stores the contents of the remote files on the server, which can be leveraged to upload arbitrary files on the affected site's server which may make remote code execution possible.

Group-Office is an enterprise customer relationship management and groupware tool. Versions prior to 26.0.9, 25.0.87, and 6.8.154 have an authenticated Remote Code Execution vulnerability in the TNEF attachment processing flow. The vulnerable path extracts attacker-controlled files from `winmail.dat` and then invokes `zip` with a shell wildcard (`*`). Because extracted filenames are attacker-controlled, they can be interpreted as `zip` options and lead to arbitrary command execution. Versions 26.0.9, 25.0.87, and 6.8.154 fix the issue.

Initiative is a self-hosted project management platform. Versions of the application prior to 0.32.4 are vulnerable to Stored Cross-Site Scripting (XSS) in the document upload functionality. Any user with upload permissions within the "Initiatives" section can upload a malicious `.html` or `.htm` file as a document. Because the uploaded HTML file is served under the application's origin without proper sandboxing, the embedded JavaScript executes in the context of the application. As a result, authentication tokens, session cookies, or other sensitive data can be exfiltrated to an attacker-controlled server. Additionally, since the uploaded file is hosted under the application's domain, simply sharing the direct file link may result in execution of the malicious script when accessed. Version 0.32.4 fixes the issue.

The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to arbitrary file uploads due to incorrect file type validation in the 'WPUF_Admin_Settings::check_filetype_and_ext' function and in the 'Admin_Tools::check_filetype_and_ext' function in all versions up to, and including, 4.2.8. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to versions 26.0.5, 27.0.2, and 28.0.0, an authenticated user with sufficient privileges can exploit a path traversal vulnerability to upload a malicious file to an arbitrary location on the server. Once uploaded, the file can be used to achieve remote code execution (RCE). An attacker must be authenticated and have the appropriate permissions to exploit this issue. If the server is configured as read-only, remote code execution (RCE) is not possible; however, the malicious file upload may still be achievable. This problem is fixed in LORIS v26.0.5 and above, v27.0.2 and above, and v28.0.0 and above. As a workaround, LORIS administrators can disable the media module if it is not being used.

Cross-Site Scripting (XSS) vulnerability in the subtitle loading function of the asbplayer Chrome Extension version 1.14.0 allows attackers to execute arbitrary JavaScript in the context of the active streaming platform via a crafted .srt subtitle file. Because the script executes within the same-site context, it can bypass cross-origin restrictions, leading to unauthorized same-site API requests and session data exfiltration.

GetSimple CMS is a content management system. All versions of GetSimple CMS do not implement CSRF protection on the administrative file upload endpoint. As a result, an attacker can craft a malicious web page that silently triggers a file upload request from an authenticated victim’s browser. The request is accepted without requiring a CSRF token or origin validation. This allows an attacker to upload arbitrary files to the application without the victim’s knowledge or consent. In order to exploit this vulnerability, the victim must be authenticated to GetSimple CMS (e.g., admin user), and visit an attacker-controlled webpage. This issue does not have a fix at the time of publication.
