Root has patched CVE-2025-59343 in the tar-fs package for Root:npm. Multiple fixed versions available.

tar-fs provides filesystem bindings for tar-stream. Versions prior to 3.1.1, 2.1.3, and 1.16.5 are vulnerable to symlink validation bypass if the destination directory is predictable with a specific tarball. This issue has been patched in version 3.1.1, 2.1.4, and 1.16.6. A workaround involves using the ignore option on non files/directories.

TuxCare rebuilt tar-fs to address 5 CVEs. Fixed in 1.5.1-tuxcare.1.

TuxCare rebuilt tar-fs to address 3 CVEs. Fixed in 3.0.4-tuxcare.1.

TuxCare rebuilt tar-fs to address 3 CVEs. Fixed in 2.1.1-tuxcare.1.
