Machine-written summary

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

Moodle versions 3.5.0 before 3.5.9, 3.6.0 before 3.6.7, and 3.7.0 before 3.7.3 do not revoke role capabilities correctly. When a cohort role assignment was removed, the associated capabilities were not always revoked, so a user could keep permissions they should have lost. The source gives few details on who can exploit this or how. Upgrade to Moodle 3.5.9, 3.6.7, 3.7.3, or later.
