| CVE-2026-33710 | Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, REST API keys are generated using md5(time() + (user_id * 5) - rand(10000, 10000)). The rand(10000, 10000) call always returns exactly 10000 (min == max), making the formula effectively md5(timestamp + user_id*5 - 10000). An attacker who knows a username and approximate key creation time can brute-force the API key. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3. | [email protected] | 7.5 | 0.03% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33708 | Chamilo LMS is a learning management system. Prior to 1.11.38, the get_user_info_from_username REST API endpoint returns personal information (email, first name, last name, user ID, active status) of any user to any authenticated user, including students. There is no authorization check. This vulnerability is fixed in 1.11.38. | [email protected] | 6.5 | 0.03% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33707 | 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. | [email protected] | 9.4 | 0.07% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33706 | Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user with a REST API key can modify their own status field via the update_user_from_username endpoint. A student (status=5) can change their status to Teacher/CourseManager (status=1), gaining course creation and management privileges. This vulnerability is fixed in 1.11.38. | [email protected] | 7.1 | 0.03% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33705 | Chamilo LMS is a learning management system. Prior to 1.11.38, Twig template files (.tpl) under /main/template/default/ are directly accessible without authentication via HTTP GET requests. These templates expose internal application logic, variable names, AJAX endpoint URLs, and admin panel structure. This vulnerability is fixed in 1.11.38. | [email protected] | 5.3 | 0.05% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33704 | Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user (including students) can write arbitrary content to files on the server via the BigUpload endpoint. The key parameter controls the filename and the raw POST body becomes the file content. While .php extensions are filtered to .phps, the .pht extension passes through unmodified. On Apache configurations where .pht is handled as PHP, this leads to Remote Code Execution. This vulnerability is fixed in 1.11.38. | [email protected] | 7.1 | 0.26% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33703 | Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the /social-network/personal-data/{userId} endpoint allows any authenticated user to access full personal data and API tokens of arbitrary users by modifying the userId parameter. This results in mass disclosure of sensitive user information and credentials, enabling a full platform data breach. This vulnerability is fixed in 2.0.0-RC.3. | [email protected] | 7.1 | 0.04% | 2026-04-10 | 2026-04-16 |

| CVE-2026-33698 | Chamilo LMS is a learning management system. Prior to 1.11.38, a chained attack can enable otherwise-blocked PHP code from the main/install/ directory and allow an unauthenticated attacker to modify existing files or create new files where allowed by system permissions. This only affects portals with the main/install/ directory still present and read-accessible. This vulnerability is fixed in 1.11.38. | [email protected] | 9.3 | 0.05% | 2026-04-10 | 2026-04-16 |
| CVE-2026-33618 | Chamilo LMS is a learning management system. Prior to .0.0-RC.3, the PlatformConfigurationController::decodeSettingArray() method uses PHP's eval() to parse platform settings from the database. An attacker with admin access (obtainable via Advisory 1) can inject arbitrary PHP code into the settings, which is then executed when any user (including unauthenticated) requests /platform-config/list. This vulnerability is fixed in 2.0.0-RC.3. | [email protected] | 8.8 | 0.05% | 2026-04-10 | 2026-04-17 |
