Descripción técnica

OpenChamber 1.11.7 contains a path traversal vulnerability in the file-serving endpoints /api/fs/read, /api/fs/stat, and /api/fs/raw that allows unauthenticated remote attackers to read arbitrary files by supplying the allowOutsideWorkspace=true query parameter alongside an absolute path, bypassing the workspace boundary check in resolveReadPathFromContext. Attackers can exploit the vacuous isPathWithinRoot guard to read sensitive files such as the JWT signing secret, SSH private keys, API credentials, and environment variables, enabling full authentication bypass by forging session cookies on password-protected deployments.

———A security vulnerability has been detected in NocteDefensor LudusMCP up to 1.0.24. The impacted element is an unknown function of the file src/tools/ludusEnvironmentGuidesSearch.ts of the component ludus_environment_guides_search. Such manipulation of the argument guide_name leads to path traversal. Local access is required to approach this attack. The project was informed of the problem early through an issue report but has not responded yet.7h CVE-2026-184277.5 ALT

———@fastify/static before version 10.1.3 contains an incomplete fix for a previous route guard bypass. The static file handler rejected only parent directory segments, but it did not canonicalize dot segments, duplicate slashes, encoded dots, or backslashes before route matching and before delegating to the send layer. As a result, an unauthenticated attacker could request a file protected by a route based guard using a non canonical path form that misses the guarded route yet resolves back onto the protected file, disclosing its contents. Applications that protect a subtree of the static root with a route based guard are affected, while applications relying on the allowedPath option are not. This is fixed in @fastify/static 10.1.3, which canonicalizes the pathname, including rejecting backslashes, on the path used for routing and serving.7h CVE-2026-281466.5 MED

———A security vulnerability has been detected in MonomythDevelopment la-forge-mcp 1.0.0. This issue affects the function screenshotElement of the file src/index.ts of the component screenshot_element Tool. Such manipulation of the argument output_name leads to path traversal. The attack can be executed remotely. Upgrading to version 1.1.1 is capable of addressing this issue. The name of the patch is 1102172c9adec4a619e241efd6bfb74f5b1f4332. Upgrading the affected component is advised. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.7h CVE-2026-189917.3 ALT

——0rclone is a command-line program to sync files and directories to and from different cloud storage providers. From v1.51.0 until v1.75.0, the local backend in backend/local/local.go relies on the configurable filename encoder to prevent remote filename data from becoming operating-system path syntax, so a local destination using Slash, None, Raw, or on Windows an encoding that preserves backslash can decode a standard-encoded fullwidth dot-dot component or native backslash form into an actual parent-directory component before filepath.Join resolves it outside the configured local root, allowing an attacker-controlled source object to create or overwrite files outside the selected destination directory as the rclone process. This issue is fixed in v1.75.0.7h
