CVE-2025-67480Public exploitNetwork attack vector

Protected page disclosure via missing API permission check

Published Feb 3, 2026 · Updated Feb 3, 2026

Information disclosure in MediaWiki before 1.39.16, 1.43.6, 1.44.3, and 1.45.1 allows remote attackers to read protected pages. The ApiQueryRevisionsBase list handlers return revision content for titles without checking the requester's read permission. Exploitation requires Lockdown with a namespace configured as non-includable and read-restricted; page titles remain visible by design, while protected revision content is exposed.
