CVE-2025-52468Network attack vector

Stored XSS via unsanitized CSV user fields

Published Mar 2, 2026 · Updated Mar 2, 2026

Stored XSS in Chamilo LMS before 1.11.30 allows remote attackers to execute JavaScript when an authenticated user views an imported profile. The two user-import handlers store CSV Last Name, First Name, and Username values without XSS filtering, allowing markup to reach profile output. Victim interaction is required: an authenticated profile view triggers the payload, and the Who is Online page also exposes unauthenticated viewers.
