CVE-2025-52469

Chamilo: Friend Request Workflow Bypass - Unauthorized Friend Addition and ID Validation Bypass

Published Mar 2, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
Chamilo is a learning management system. Prior to version 1.11.30, a logic vulnerability in the friend request workflow of Chamilo’s social network module allows an authenticated user to forcibly add any user as a friend by directly calling the AJAX endpoint. The attacker can bypass the normal flow of sending and accepting friend requests, and even add non-existent users. This breaks access control and social interaction logic, with potential privacy implications. This issue has been patched in version 1.11.30.
