Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Gotify server versions 2.9.1 and earlier (github.com/gotify/server/v2) and versions before 3.0.0 (github.com/gotify/server/v3) let the password change endpoint run without the current password. An attacker holding a valid client token can set a new password for the affected user, and recovery requires an administrator or direct database access. Upgrade the v3 module to 3.0.0, which requires re-authentication to change a password; no fixed version is listed for v2.
