Chamilo

Chamilo LMS versions prior to 1.11.38 and 2.0.0-RC.3 are vulnerable to a weak password reset mechanism, allowing attackers to compute password reset tokens using only a user's email address due to the use of SHA1 hashing without randomization, expiration, or rate limiting, leading to unauthorized account takeover.

Chamilo LMS versions prior to 2.0.0-RC.3 are vulnerable to remote code execution (RCE) via eval injection, where an authenticated administrator can inject arbitrary PHP code into platform settings that is then executed when any user (including unauthenticated) requests the /platform-config/list endpoint.

A Server-Side Request Forgery (SSRF) vulnerability exists in Chamilo LMS versions prior to 1.11.38 and 2.0.0-RC.3, allowing authenticated attackers to make arbitrary HTTP requests, scan internal ports, and access cloud instance metadata via the Social Wall feature.

Chamilo LMS versions prior to 1.11.38 and 2.0.0-RC.3 generate predictable REST API keys, allowing attackers with knowledge of a username and approximate key creation time to brute-force access.

An Insecure Direct Object Reference (IDOR) vulnerability in Chamilo LMS (CVE-2026-32930) allows authenticated teachers to modify gradebook evaluation settings of other courses by manipulating the 'editeval' GET parameter, leading to unauthorized data modification.

An unrestricted file upload vulnerability in Chamilo LMS (CVE-2026-32931) allows an authenticated teacher to upload a PHP webshell, leading to remote code execution.

Chamilo LMS versions prior to 1.11.38 are vulnerable to remote code execution via arbitrary file upload by authenticated users due to insufficient file extension filtering in the BigUpload endpoint, allowing execution of PHP code on servers configured to process .pht files.
