CVE-2026-62684Public exploitNetwork attack vector

Share secret disclosure via direct struct serialization

Published Aug 18, 2026 · Updated Aug 18, 2026

Information disclosure in File Browser before 2.63.17 allows remote authenticated users to read share password hashes and bypass tokens via the share API. sharePostHandler, shareListHandler, and shareGetsHandler pass the share.Link storage struct to renderJSON, so json.Marshal emits the password_hash and token fields instead of a filtered response object. Any authenticated user can recover secrets for that user's password-protected shares, and an administrator listing shares can collect every user's secrets for offline cracking and direct access to protected shares.
