CVSS 3.1
9.1 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NCVE-2026-42496
Critical (9.1) in archive\ \. EPSS 0.5% chance of exploitation in the next 30 days.
Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory.
_make_special_file() passes the tar header's linkname to symlink() without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular file extraction does not cover the symlink target.
A subsequent open through the extracted name reads or writes the attacker chosen path.
