3.6 · LOWgpgtar in GnuPG before 2.5.19 can allow file overwrite via crafted data in an archive.
Overview
CVE-2026-105712 is a low-severity vulnerability. It was published on October 5, 2026 and has a CVSS 3.1 base score of 3.6 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.6, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical description
gpgtar in GnuPG before 2.5.19 can allow file overwrite via crafted data in an archive. When extracting an untrusted archive with --directory (aka -C) into an existing directory containing a pre-existing symlink, gpgtar can follow that symlink and create or overwrite a file outside the selected extraction directory. The write is limited by the extraction user's filesystem permissions. An archive extracted into a fresh empty directory does not have this risk.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. 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.
