CVE-2026-19672

Name of the Vulnerable Software and Affected Versions Python (affected versions not specified)

Description In the tarfile module, the tar and data extraction filters allow the creation of empty directories outside the intended destination on POSIX platforms. This occurs when a member name leaves the destination and subsequently returns to it, such as ../evil/../dest/sub/file. While the containment check utilizes the resolved path, intermediate directories are created based on the provided name. Member contents remain extracted within the destination. This issue does not affect Windows because .. components are collapsed before reaching the filesystem.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
