CVE-2025-23080Network attack vector

Cross-site scripting via undisclosed BadgeView output handling

Published Jan 14, 2025 · Updated Jan 14, 2025

Cross-site scripting in MediaWiki OpenBadges on affected branches before 1.39.11, 1.41.3, or 1.42.2 allows remote attackers to run script. Wikimedia identifies Special:BadgeView as the locus, but its public record and release notice do not disclose which input reaches output without neutralization. Network access without authentication is sufficient, and the published assessment limits the consequence to disclosure within the browser context.
