CVE-2026-20613: Apple Container

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The ArchiveReader.extractContents() function used by cctl image load and container image load performs no pathname validation before extracting an archive member. This means that a carelessly or maliciously constructed archive can extract a file into any user-writable location on the system using relative pathnames. This issue is addressed in container 0.8.0 and containerization 0.21.0.

Affected products

• Apple Container: before 0.8.0 (fixed in 0.8.0)
• Apple Containerization: before 0.21.0 (fixed in 0.21.0)
