CVE-2024-47848Network attack vector

Blocked-account review changes via missing block check

Published Oct 4, 2024 · Updated Oct 7, 2024

Authorization bypass in Wikimedia Foundation PageTriage allows remote attackers with blocked accounts to review or unreview articles. The pagetriageaction API accepts review-state writes without rejecting a caller whose MediaWiki account is blocked. Exploitation requires a blocked account that can still reach the API, and the bounded effect is unauthorized alteration of article review status and exposure of associated review information.
