GHSA-9XWG-3R6F-JCX2 PyMdown Extensions: Path traversal in the b64 extension lets <img src> read files outside base_path

Summary The b64 extension inlines images referenced by as base64 data URIs. When resolving the src path it joins it onto the configured basepath with os.path.normpath and opens the result directly, with no check that the resolved path stays inside basepath. A src containing ../ sequences, or an...

decompress: @xhmikosr/decompress: Decompress: Arbitrary file read/write via crafted archive extraction

A flaw was found in the decompress package for Node.js. A remote attacker can exploit this vulnerability by crafting a malicious archive. When the archive is extracted, it can create files and links outside the intended directory, leading to unauthorized reading or writing of files. This is due t...

CVE-2026-61443

PraisonAI before 1.6.78 contains a remote code execution vulnerability in SkillTools.runskillscript that executes scripts without path containment validation. Attackers can supply absolute file paths to execute arbitrary scripts from any filesystem location, including those outside the intended...

CVE-2026-53486

CVE-2026-53486

The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink...

CVE-2026-53486 decompress: Archive extraction can create files and links outside the target directory

The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink...

CVE-2026-53486

The CVE affects the Node.js decompress package used for archive extraction. Before versions 10.2.1 and 11.1.3, crafted archives could read or write files outside the target directory due to: hardlink and symlink entries being created without proper target checks; path containment validated by a s...

PYSEC-2026-2556 LangChain: Path traversal and sandbox escape in LangChain file-search middleware and loaders

Summary Several LangChain components that resolve filesystem paths or expand search patterns do not consistently confine the resolved path to the intended root directory. Affected behaviors include: a file-search agent middleware that validates a starting directory but not the search pattern or t...

CVE-2026-39245

decompress before 4.2.2 contains an improper path containment check that enables directory traversal and arbitrary file write. The safeMakeDir function index.js line 29 and the extraction path validation index.js line 106 use String.indexOf to verify the resolved path is within the output...

CVE-2026-39245

CVE-2026-39245 affects the decompress package (before 4.2.2). The vulnerability arises from an improper path containment check during extraction: safeMakeDir (index.js:29) and extraction path validation (index.js:106) rely on realDestinationDir.indexOf(realOutputPath) !== 0. This boundary check f...

GHSA-4GXV-P5G5-J7W7 gonic has arbitrary file write in createPlaylist: any authenticated user can write playlist M3U content to attacker-controlled path on the host

Summary A logic error in ServeCreateOrUpdatePlaylist allows any authenticated Subsonic user including non-admin to write playlist M3U content to an attacker-controlled absolute filesystem path on the gonic host, and to create intermediate directories with 0o777 permissions. The bug is independent...
