#vulnerability

### Impact The HTTP Gateway processes headers, but with no timeout set. With a Slowloris attack, an attacker could cause Denial of Service (DoS). Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. ### Patches Patch has been implemented by [commit `1385bd8`](https://github.com/ctfer-io/chall-manager/commit/1385bd869142651146cd0b123085f91cec698636) and shipped in [`v0.1.4`](https://github.com/ctfer-io/chall-manager/releases/tag/v0.1.4). ### Workarounds No workaround exist. ### References N/A

### Impact When decoding a scenario (i.e. a zip archive), the size of the decoded content is not checked, potentially leading to zip bombs decompression. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. ### Patches Patch has been implemented by [commit `14042aa`](https://github.com/ctfer-io/chall-manager/commit/14042aa66a577caee777e10fe09adcf2587d20dd) and shipped in [`v0.1.4`](https://github.com/ctfer-io/chall-manager/releases/tag/v0.1.4). ### Workarounds No workaround exist. ### References N/A.

### Impact When decoding a scenario (i.e. a zip archive), the path of the file to write is not checked, potentially leading to zip slips. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is **highly** recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. ### Patches Patch has been implemented by [commit `47d188f`](https://github.com/ctfer-io/chall-manager/commit/47d188fda5e3f86285e820f12ad9fb6f9930662c) and shipped in [`v0.1.4`](https://github.com/ctfer-io/chall-manager/releases/tag/v0.1.4). ### Workarounds No workaround exist. ### References N/A.

## Summary The expression evaluation feature in pdfme 5.2.0 to 5.4.0 contains critical vulnerabilities allowing sandbox escape leading to XSS and prototype pollution attacks. ## Details ### 1. Sandbox Escape Leading to XSS The expression evaluator's sandbox can be bypassed to execute arbitrary JavaScript code. Attackers can obtain the Function constructor through indirect methods: ```javascript // Attack vector 1: Using Object.getOwnPropertyDescriptor { ((f, g) => f(g(Object), "constructor").value)(Object.getOwnPropertyDescriptor, Object.getPrototypeOf)("alert(location)")() } // Attack vector 2: Using object property access { { f: Object.getOwnPropertyDescriptor }.f({ g: Object.getPrototypeOf }.g(Object), "constructor").value("alert(location)")() } ``` Both payloads bypass the sandbox restrictions and execute `Function("alert(location)")()`. ### 2. Prototype Pollution The expression evaluator allows access to prototype accessor methods which can be exploited with Object.assign ...

An SQL injection vulnerability in the `EventCache::find_event_with_relations` method of matrix-sdk 0.11 and 0.12 allows malicious room members to execute arbitrary SQL commands in Matrix clients that directly pass relation types provided by those room members into this method, when used with the default sqlite-based store backend. Exploitation is unlikely, as no known clients currently use the API in this manner. ### Workarounds Passing only trusted (or sanitised) relation types to the `filter` argument of `EventCache::find_event_with_relations()` avoids the issue. ### Patches The issue is fixed in matrix-sdk 0.13. ### References The issue was introduced in https://github.com/matrix-org/matrix-rust-sdk/pull/4849.

Cybersecurity researchers have discovered a critical vulnerability in the open-source mcp-remote project that could result in the execution of arbitrary operating system (OS) commands. The vulnerability, tracked as CVE-2025-6514, carries a CVSS score of 9.6 out of 10.0. "The vulnerability allows attackers to trigger arbitrary OS command execution on the machine running mcp-remote when it

### Impact The Parse Server GraphQL API previously allowed public access to the GraphQL schema without requiring a session token or the master key. While schema introspection reveals only metadata and not actual data, this metadata can still expand the potential attack surface. ### Patches The issue has been addressed by requiring the master key for schema introspection. Additionally, a new Parse Server configuration option, `graphQLPublicIntrospection`, has been introduced. This option allows developers to re-enable public schema introspection if their application relies on it. However, it is strongly recommended to use this option only temporarily and to update the application to function without depending on public introspection. ### Workarounds None available. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-48q3-prgv-gm4w - Fix for Parse Server 7: https://github.com/parse-community/parse-server/pull/9820 - F...

A flaw was found in Keycloak. When an authenticated attacker attempts to merge accounts with another existing account during an identity provider (IdP) login, the attacker will subsequently be prompted to "review profile" information. This vulnerability allows the attacker to modify their email address to match that of a victim's account, triggering a verification email sent to the victim's email address. The attacker's email address is not present in the verification email content, making it a potential phishing opportunity. If the victim clicks the verification link, the attacker can gain access to the victim's account.

A vulnerability in the DocugamiReader class of the run-llama/llama_index repository, up to but excluding version 0.12.41, involves the use of MD5 hashing to generate IDs for document chunks. This approach leads to hash collisions when structurally distinct chunks contain identical text, resulting in one chunk overwriting another. This can cause loss of semantically or legally important document content, breakage of parent-child chunk hierarchies, and inaccurate or hallucinated responses in AI outputs. The issue is resolved in version 0.3.1.

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed two vulnerabilities each in Asus Armoury Crate and Adobe Acrobat products.
