AI-suggested
A fix is available and was introduced in commit 6c78164. Users should upgrade to a version of unearth that includes this commit or later to remediate the vulnerability. Until patched, avoid processing untrusted tar archives with unearth.
Description
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.
