Published: 06 March 2026
Summary
CVE-2025-59541 is a high-severity CSRF (CWE-352) vulnerability in Chamilo Chamilo Lms. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 4.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-23 (Session Authenticity) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-59541 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, affecting Chamilo, an open-source learning management system. Versions prior to 1.11.34 are vulnerable due to the absence of anti-CSRF protections, such as tokens, on sensitive actions like project deletion within courses. These actions rely on GET-based requests, enabling unauthorized execution when triggered inadvertently.
An unauthenticated attacker (PR:N) can exploit this over the network (AV:N) with low complexity (AC:L) by tricking an authenticated Trainer user into visiting a malicious webpage (UI:R). The forged request deletes projects inside a course without the victim's consent, leading to high integrity (I:H) and availability (A:H) impacts but no confidentiality loss (C:N), with an unchanged scope (S:U). The CVSS v3.1 base score is 8.1.
The issue was patched in Chamilo version 1.11.34. Mitigation involves upgrading to this version or later. Additional details are available in the GitHub release notes at https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.34 and the security advisory at https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-rpj6-p9m5-q637.

not implement anti-CSRF protections (tokens) and GET based requests. As a result, an authenticated user (Trainer) can be tricked into executing this unwanted action by simply visiting a malicious page. This issue has been patched in version 1.11.34.
