CVE-2023-45369Network attack vector

Authenticated disclosure of hidden usernames

Published Oct 9, 2023 · Updated Sep 19, 2024

Information disclosure in PageTriage for MediaWiki before 1.35.12 allows remote authenticated users to view hidden usernames via the pagetriagelist API. The API and PageTriage toolbar return revision-author metadata without suppressing names marked hidden, exposing identities that oversight controls should conceal. Access requires a logged-in account able to review PageTriage items; the demonstrated consequence is confidentiality loss of suppressed usernames without evidence of data modification or service interruption.
