Description
Semantic MediaWiki 3.0.0 before 7.4.1 contains an uncontrolled recursion vulnerability in the ElasticStore ConceptDescriptionInterpreter that only detects directly self-referencing concepts. Users with page-edit rights can create mutually referencing concept pages, causing concept page views, Special:Ask, or api.php action=ask queries to exhaust PHP memory or stack.
