CVE-2026-20613

Apple Containerization path traversal

7.8 HIGHPublic exploitEPSS 0.28%
  1. Published22 Jan 2026

Description

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.
