There is a HIGH severity vulnerability affecting CPython. In CPython 3.13 and earlier, the tarfile module's data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link. Such archives may cause extraction to modify the permissions or modification time of a file outside the destination directory, or expose the contents of that file within the extracted tree.
Please see the linked CVE ID for the latest information on affected versions: * https://www.cve.org/CVERecord?id=CVE-2026-82049 * https://github.com/python/cpython/pull/157192 -- Stan Ulbrych (https://stan.ulbrych.org)
