CVE-2025-48387: Mafintosh Tar-Fs

High severity, CVSS 8.7. EPSS: 0.6% chance of exploitation in the next 30 days.

tar-fs provides filesystem bindings for tar-stream. Versions prior to 3.0.9, 2.1.3, and 1.16.5 have an issue where an extract can write outside the specified dir with a specific tarball. This has been patched in versions 3.0.9, 2.1.3, and 1.16.5. As a workaround, use the ignore option to ignore non files/directories.

Affected products

• Mafintosh Tar-Fs: before 1.16.5 (fixed in 1.16.5); from 2.0.0, before 2.1.3 (fixed in 2.1.3); from 3.0.0, before 3.0.9 (fixed in 3.0.9)
