Description
Yank Note before 3.93.1 contains a path traversal vulnerability that allows unauthenticated remote attackers to read arbitrary files via the path or doc parameter of /api/help. Attackers can supply repeated '../' segments, which bypass the single-replacement sanitization in the publicly allowlisted endpoint, to read SSH keys, configuration, or notes.
