CVE-2024-4892Network attack vector

Subscriber-level stored XSS via unescaped display names

Published Jun 12, 2024 · Updated Apr 8, 2026

Stored XSS in the Members block in BuddyPress before 12.5.1 allows remote authenticated users to inject scripts through display names. The renderer in bp-members-blocks.php places a member's display_name value into generated member markup without sufficient sanitization and output escaping, leaving stored script content executable. Subscriber-level access is sufficient, and the payload runs in a visitor's browser when the affected Members block is viewed.
