CVE-2026-59871 PUBLISHED

node-tar: Process crash via PAX numeric path type confusion

Assigner: GitHub_M
Reserved: 07.07.2026 Published: 08.07.2026 Updated: 08.07.2026

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, node-tar coerces all-digit PAX path and linkpath values in src/pax.ts to JavaScript numbers, causing downstream path handling such as normalizeWindowsPath(entry.path).split('/') to throw an uncaught TypeError. This issue is fixed in version 7.5.18.
