Vulnerabilidad · Publicado 10/08/2026
unearth through 0.18.2, fixed in commit 6c78164, contains a path traversal vulnerability in the is_within_directory function that fails to normalize paths before validation, allowing ../ sequences to bypass directory containment checks. Attackers can supply malicious tar archives with symlink members or traversal sequences to write files to arbitrary filesystem locations accessible to the process.
