CVE-2025-32698Public exploitNetwork attack vector

Suppressed log disclosure via swapped restriction constants

Published Apr 10, 2025 · Updated Nov 3, 2025

Information disclosure in MediaWiki before 1.39.12, 1.42.6, and 1.43.1 allows remote authenticated users to reveal suppressed log data. LogPager.php's enforceActionRestrictions() and enforcePerformerRestrictions() compare log_deleted bits against the opposite suppression constants, causing filtered searches to return entries for suppressed targets or performers. An account with deletedhistory but without suppression rights must know or brute-force a suppressed title or username; the disclosure confirms its existence and associated log activity.
