Lifecycle Timeline
4DescriptionGitHub Advisory
Lychee is a free, open-source photo-management tool. Prior to 7.1.0, an authorization vulnerability exists in Lychee's album password unlock functionality that allows users to gain possibly unauthorized access to other users' password-protected albums. When a user unlocks a password-protected public album, the system automatically unlocks ALL other public albums that share the same password, resulting in a complete authorization bypass. This vulnerability is fixed in 7.1.0.
AnalysisAI
Lychee photo management tool versions before 7.1.0 contain an authorization bypass in the album password unlock mechanism that allows authenticated users to access multiple password-protected albums by unlocking just one that shares the same password. Public exploit code exists for this vulnerability. Administrators should upgrade to version 7.1.0 or later to prevent unauthorized access to protected photo collections.
