Yank Note before 3.93.1 Path Traversal via /api/help Endpoint

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.

Yank Note (YN) 3.52.1 allows execution of arbitrary code when a crafted file is opened, e.g., via nodeRequire('child_process').
