CVE Database - Input Validation

A weakness has been identified in JeecgBoot 3.9.1. This vulnerability affects the function importDocumentFromZip of the file org/jeecg/modules/airag/llm/controller/AiragKnowledgeController.java of the component Retrieval-Augmented Generation. Executing a manipulation can lead to deserialization. The attack can be launched remotely. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. The project was informed of the problem early through an issue report but has not responded yet.

An improper input validation and protocol compliance vulnerability in free5GC v4.0.1 allows remote attackers to cause a denial of service. The UPF incorrectly accepts a malformed PFCP Association Setup Request, violating 3GPP TS 29.244. This places the UPF in an inconsistent state where a subsequent valid PFCP Session Establishment Request triggers a cascading failure, disrupting the SMF connection and causing service degradation.

### Summary The `arrayLimit` option in qs does not enforce limits for comma-separated values when `comma: true` is enabled, allowing attackers to cause denial-of-service via memory exhaustion. This is a bypass of the array limit enforcement, similar to the bracket notation bypass addressed in GHSA-6rw7-vpxm-498p (CVE-2025-15284). ### Details When the `comma` option is set to `true` (not the default, but configurable in applications), qs allows parsing comma-separated strings as arrays (e.g., `?param=a,b,c` becomes `['a', 'b', 'c']`). However, the limit check for `arrayLimit` (default: 20) and the optional throwOnLimitExceeded occur after the comma-handling logic in `parseArrayValue`, enabling a bypass. This permits creation of arbitrarily large arrays from a single parameter, leading to excessive memory allocation. **Vulnerable code** (lib/parse.js: lines ~40-50): ```js if (val && typeof val === 'string' && options.comma && val.indexOf(',') > -1) {     return val.split(','); } if (options.throwOnLimitExceeded && currentArrayLength >= options.arrayLimit) {     throw new RangeError('Array limit exceeded. Only ' + options.arrayLimit + ' element' + (options.arrayLimit === 1 ? '' : 's') + ' allowed in an array.'); } return val; ``` The `split(',')` returns the array immediately, skipping the subsequent limit check. Downstream merging via `utils.combine` does not prevent allocation, even if it marks overflows for sparse arrays.This discrepancy allows attackers to send a single parameter with millions of commas (e.g., `?param=,,,,,,,,...`), allocating massive arrays in memory without triggering limits. It bypasses the intent of `arrayLimit`, which is enforced correctly for indexed (`a[0]=`) and bracket (`a[]=`) notations (the latter fixed in v6.14.1 per GHSA-6rw7-vpxm-498p). ### PoC **Test 1 - Basic bypass:** ``` npm install qs ``` ```js const qs = require('qs'); const payload = 'a=' + ','.repeat(25); // 26 elements after split (bypasses arrayLimit: 5) const options = { comma: true, arrayLimit: 5, throwOnLimitExceeded: true }; try {   const result = qs.parse(payload, options);   console.log(result.a.length); // Outputs: 26 (bypass successful) } catch (e) {   console.log('Limit enforced:', e.message); // Not thrown } ``` **Configuration:** - `comma: true` - `arrayLimit: 5` - `throwOnLimitExceeded: true` Expected: Throws "Array limit exceeded" error. Actual: Parses successfully, creating an array of length 26. ### Impact Denial of Service (DoS) via memory exhaustion.

Adminer is open-source database management software. Adminer v5.4.1 and earlier has a version check mechanism where adminer.org sends signed version info via JavaScript postMessage, which the browser then POSTs to ?script=version. This endpoint lacks origin validation and accepts POST data from any source. An attacker can POST version[] parameter which PHP converts to an array. On next page load, openssl_verify() receives this array instead of string and throws TypeError, returning HTTP 500 to all users. Upgrade to Adminer 5.4.2.

A security vulnerability has been detected in yuan1994 tpadmin up to 1.3.12. This affects an unknown part in the library /public/static/admin/lib/webuploader/0.1.5/server/preview.php of the component WebUploader. The manipulation leads to deserialization. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

n8n is an open source workflow automation platform. Prior to 1.121.0, there is a vulnerability in the HTTP Request node's credential domain validation allowed an authenticated attacker to send requests with credentials to unintended domains, potentially leading to credential exfiltration. This only might affect user who have credentials that use wildcard domain patterns (e.g., *.example.com) in the "Allowed domains" setting. This issue is fixed in version 1.121.0 and later.

Claude Code is an agentic coding tool. Prior to version 2.0.55, Claude Code failed to properly validate commands using piped sed operations with the echo command, allowing attackers to bypass file write restrictions. This vulnerability enabled writing to sensitive directories like the .claude folder and paths outside the project scope. Exploiting this required the ability to execute commands through Claude Code with the "accept edits" feature enabled. This issue has been patched in version 2.0.55.

Claude Code is an agentic coding tool. Prior to version 2.0.57, Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.57.

A security issue was discovered in ingress-nginx where the `nginx.ingress.kubernetes.io/auth-proxy-set-headers` Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)

A vulnerability has been found in bolo-solo up to 2.6.4. This impacts the function importMarkdownsSync of the file src/main/java/org/b3log/solo/bolo/prop/BackupService.java of the component SnakeYAML. Such manipulation leads to deserialization. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.

fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. In versions 5.0.9 through 5.3.3, a RangeError vulnerability exists in the numeric entity processing of fast-xml-parser when parsing XML with out-of-range entity code points (e.g., `&#9999999;` or `&#xFFFFFF;`). This causes the parser to throw an uncaught exception, crashing any application that processes untrusted XML input. Version 5.3.4 fixes the issue.

A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack.

PolarLearn is a free and open-source learning program. Prior to version 0-PRERELEASE-15, the vote API route (`POST /api/v1/forum/vote`) trusts the JSON body’s `direction` value without runtime validation. TypeScript types are not enforced at runtime, so an attacker can send arbitrary strings (e.g., `"x"`) as `direction`. Downstream (`VoteServer`) treats any non-`"up"` and non-`null` value as a downvote and persists the invalid value in `votes_data`. This can be exploited to bypass intended business logic. Version 0-PRERELEASE-15 fixes the vulnerability.

pwn.college DOJO is an education platform for learning cybersecurity. Prior to commit e33da14449a5abcff507e554f66e2141d6683b0a, missing sandboxing on `/workspace/*` routes allows challenge authors to inject arbitrary javascript which runs on the same origin as `http[:]//dojo[.]website`. This is a sandbox escape leading to arbitrary javascript execution as the dojo's origin. A challenge author can craft a page that executes any dangerous actions that the user could. Version e33da14449a5abcff507e554f66e2141d6683b0a patches the issue.

The backup restore function does not properly validate unexpected or unrecognized tags within the backup file. When such a crafted file is restored, the injected tag is interpreted by a shell, allowing execution of arbitrary commands with root privileges. Successful exploitation allows the attacker to gain root-level command execution, compromising confidentiality, integrity and availability.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-RunPkgStatusRequest instruction. Improper input validation allows authenticated attackers with actioner privilege to run elevated arbitrary commands on connected hosts via malicious commands injected into the instruction’s input field. Users of 1E Client version 24.5 or higher are not affected.

A missing validation of a user-controlled value in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to tamper with log timestamps via crafted UDP Sync command. This could result in forged or nonsensical datetime prefixes and compromising log integrity and forensic correlation.

A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to inject, tamper with, or forge log entries in \Nomad Branch.log via crafted data sent to the UDP network handler. This can impact log integrity and nonrepudiation.

iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Versions prior to 2.3.1.2 have an undefined behavior issue when floating-point NaN values are converted to unsigned short integer types during ICC profile XML parsing potentially corrupting memory structures and enabling arbitrary code execution. This vulnerability affects users of the iccDEV library who process ICC color profiles. ICC Profile Injection vulnerabilities arise when user-controllable input is incorporated into ICC profile data or other structured binary blobs in an unsafe manner. Version 2.3.1.2 contains a fix for the issue. No known workarounds are available.

An input validation vulnerability in the oneflow.index_add component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.

An input validation vulnerability in the flow.arange() component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.

Sync Breeze Enterprise Server v10.4.18 and Disk Pulse Enterprise v10.4.18 contain a remote denial-of-service (DoS) vulnerability in the configuration restore functionality. The issue is due to insufficient validation of user-supplied data during this process. An attacker could send malicious requests to alter the configuration file, causing the application to become unresponsive. In a successful scenario, the service may not recover on its own and require a complete reinstallation, as the configuration becomes corrupted and prevents the service from restarting, even manually.

By sending crafted files to the firmware update endpoint of Tapo C220 v1 and C520WS v2, the device terminates core system services before verifying authentication or firmware integrity. An unauthenticated attacker can trigger a persistent denial of service, requiring a manual reboot or application initiated restart to restore normal device operation.

The HTTP parser of Tapo C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An unauthenticated attacker can force repeated service crashes or device reboots, causing denial of service.

The kernel driver of CPUID CPU-Z v2.17 and earlier does not validate user-supplied values passed via its IOCTL interface, allowing an attacker to access sensitive information via a crafted request.
