Does this matter?

Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.

Description

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.
