  "details": "Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, the default password reset mechanism generates tokens using sha1($email) with no random component, no expiration, and no rate limiting. An attacker who knows a user's email can compute the reset token and change the victim's password without authentication. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.",
