# CVE-2026-19672: tarfile extraction filter bypass allows creation of directories outside the destination CVE-2026-19672 is fixed in 56 products on 3 platforms, first by DEBIAN-CVE-2026-19672, released September 12, 2026. 12 other affected products have no fix yet. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2026-19672 - Priority: Routine - CVSS: 6.3 (Moderate) - EPSS: 0.0047 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Aug 19, 2026 - Weakness: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-19672 ## Description The tarfile module's tar and data extraction filters created directories outside the destination for members whose name leaves the destination and returns to it, such as ../evil/../dest/sub/file. The containment check used the resolved path, but intermediate directories were created from the name as given. Only empty directories are created outside the destination. Member contents are still extracted inside it. To return to the destination the member's name must contain the destination directory's own final component, so extraction into a secure randomised directory is not affected. This affects POSIX platforms only. On Windows, .. components are collapsed before the path reaches the filesystem, so the directories outside the destination are never created. ## Where it's fixed | Platform | Product | Fixed in | Fix
