What is CVE-2026-29041?

Chamilo LMS prior to version 1.11.34 is susceptible to an authenticated remote code execution vulnerability due to inadequate validation of uploaded files. The system primarily relies on MIME-type checks and neglects thorough validation of file extensions and secure server-side storage protocols. This oversight allows authenticated low-privileged users to upload malicious files that may execute arbitrary commands on the server, leading to severe security implications. It is crucial for users running older versions of Chamilo LMS to upgrade to version 1.11.34 or later to mitigate this risk.

Affected Version(s)
