CVE-2026-105712
Low 3.6
In plain English
A low-severity security flaw in GnuPG from GnuPG. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 2% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
