Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
RuoYi versions up to and including 4.8.0 have insecure permissions that let an authenticated user escalate privileges by assigning themselves higher-level roles. The attacker needs a valid login account, and the source gives few further details on how the role assignment works. No fixed version is listed.
