CVE-2026-45144

Full vulnerability record from the local CVENow database.

Description

Chamilo LMS is an open-source learning management system. From 2.0.0 until 2.0.1, `GET /user/{username}` is anonymously reachable and renders six user-editable profile fields (`firstname`, `lastname`, `competences`, `openarea`, `teach`, and `diplomas`) inside `{% autoescape false %}`, without server-side sanitization on the write path. A ROLE_STUDENT attacker can plant HTML in their own profile; self-registration, when enabled, lets an otherwise anonymous attacker obtain that role. The stored content executes in the browser of any visitor, including administrators, who follows the public profile link, potentially allowing account takeover through session, JWT, or `localStorage` exfiltration. This issue is fixed in version 2.0.1.
