Deno: Permission Bypass via Unicode Normalization Mismatch on macOS (APFS)

Summary Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done at the raw-byte level while the APFS filesystem treats different...

node-tar: tar: node-tar: Arbitrary file overwrite via Unicode path collision race condition

A flaw was found in node-tar, a library for Node.js. This race condition vulnerability occurs due to incomplete handling of Unicode path collisions within the path-reservations system on case-insensitive filesystems, such as macOS APFS. A remote attacker can exploit this by providing a specially...

Security Bulletin: IBM Watson Discovery Cartridge affected by vulnerability in tar-6.2.1.tgz

Summary IBM Watson Discovery Cartridge affected by vulnerability in tar-6.2.1.tgz Vulnerability Details CVEID:CVE-2026-23950 DESCRIPTION: node-tar,a Tar for Node.js, has a race condition vulnerability in versions up to and including 7.5.3. This is due to an incomplete handling of Unicode path...

Important: nodejs24

Issue Overview: node-tar is a Tar for Node.js. The node-tar library = 7.5.2 fails to sanitize the linkpath of Link hardlink and SymbolicLink entries when preservePaths is false the default secure behavior. This allows malicious archives to bypass the extraction root restriction, leading to...
