YesWiki before 4.6.7 contains an empty-filter scope bypass in the triples delete API that allows any authenticated user to delete or forge arbitrary semantic triples regardless of ownership. Attackers can send an empty filter to the triples delete endpoint to remove the admins-group membership triple, emptying the admin group and causing a site-wide authorization lockout.
