CVE-2022-24813Network attack vector

Anonymous comment submission via unchecked POST path

Published Apr 4, 2022 · Updated Apr 23, 2025

Authentication bypass in Miraheze CreateWiki before d0ae798 allows remote attackers to submit anonymous queue comments. RequestWikiRequestViewer::submitForm accepted the submit-comment action and called addComment without first rejecting an anonymous form user. A direct POST to Special:RequestWikiQueue reaches the path without authentication and adds attacker-controlled text to a wiki request; no confidentiality or availability impact is reported.
