CVE-2026-22784Network attack vector

Cross-user album disclosure via password propagation

Published Jan 12, 2026 · Updated Jan 12, 2026

Incorrect authorization in Lychee before 7.1.0 allows remote attackers to read other users' password-protected public albums. The Unlock::propagate method in app/Actions/Album/Unlock.php applies one valid album password to every public album sharing that password without checking album ownership. Exploitation requires a multi-user installation, password reuse across public albums, and a session that unlocks one matching album; access is read-only.
