CVE-2026-32931Network attack vector

Authenticated code execution via MIME-only sound upload

Published Apr 10, 2026 · Updated Apr 10, 2026

Unrestricted file upload in Chamilo LMS before 1.11.38 and 2.0.0-RC.3 allows remote authenticated users to execute PHP code. Exercise::updateSound() trusts the client-supplied multipart Content-Type, preserves the original .php filename, and moves the file into a web-accessible audio directory. Teacher privileges are required; a crafted audio upload yields command execution as the web server user and permits server data access or modification.
