9.1 · CRITICALOverview
CVE-2026-42496 is a critical-severity vulnerability affecting archive\ \. It was published on May 26, 2026 and has a CVSS 3.1 base score of 9.1 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from archive\. Update \ to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
