CVE-2026-45144: Chamilo LMS stored XSS in user profile fields

CVE-2026-45144 · Severity: high · CVSS 8.9 · Published 2026-10-30

Chamilo LMS, an open-source learning management system, allows unauthenticated access to public user profiles that display six user-editable fields without proper sanitization. An attacker with a student role (or obtained through self-registration) can inject malicious HTML/JavaScript into their profile, which then executes in the browsers of other users—including administrators—who visit that profile, enabling session hijacking or account takeover.

Technical details

A stored cross-site scripting (XSS) vulnerability exists in the GET /user/{username} endpoint, which is publicly accessible and renders user profile fields (firstname, lastname, competences, openarea, teach, diplomas) within an unescaped Twig template block (`{% autoescape false %}`) without server-side sanitization. An attacker with ROLE_STUDENT can plant arbitrary HTML; if self-registration is enabled, an otherwise anonymous attacker can register, obtain student role, and craft malicious content. The injected payload executes for all visitors, including high-privilege administrators.

Affected products
