1) Path traversal (CVE-ID: N/A)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: 8.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to write arbitrary files outside the worktree.

The vulnerability exists due to path traversal in applyTreeChanges when applying tree changes during git cherry-pick. A remote user can supply a crafted repository state containing a tracked symlink and a cherry-picked tree entry to write arbitrary files outside the worktree.

User interaction is required to perform the cherry-pick operation.
