Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Admidio versions 5.0.0 up to but not including 5.0.7 are affected. The delete, activate and deactivate role actions in the groups and roles module do not validate the anti-CSRF token. An attacker who knows a role's identifier can host a forged form that, when visited by a logged-in user with the rol_assign_roles right, deletes or toggles that role, with permanent deletion removing its memberships. Upgrade to Admidio 5.0.7 or later. The source gives no other workaround.
