    CVE-2026-23950

    node-tar has Race Condition in Path Reservations via Unicode Ligature Collisions on macOS APFS

    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 collisions in the `path-reservations` system. On case-insensitive or normalization-insensitive filesyst…

    node-tar Vulnerable to Arbitrary File Overwrite and Symlink Poisoning via Insufficient Path Sanitization

    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 r…

    node-tar Vulnerable to Arbitrary File Creation/Overwrite via Hardlink Path Traversal

    node-tar,a Tar for Node.js, contains a vulnerability in versions prior to 7.5.7 where the security check for hardlink entries uses different path resolution semantics than the actual hardlink creation logic. This mismatch allows an attacker to craft a malicio…

    Prototype Pollution Vulnerability in Lodash _.unset and _.omit functions

    The _.unset and _.omit functions in Lodash are vulnerable to prototype pollution. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their ori…
