CVE-2026-32894
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedChamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the gradebook result view page allows any authenticated teacher to delete any student's grade result across the entire platform by manipulating the delete_mark or resultdelete GET parameters. No ownership or course-scope verification is performed. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe code follows a pointer that is null, crashing the process. An attacker who can reliably trigger it turns the crash into a denial of service. The fix is checking for null before use and handling the failure path gracefully.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.11.38
Upgrade to Chamilo LMS 1.11.38 or later (1.x branch), or 2.0.0-RC.3 or later (2.x branch)
- 1. Backup the Chamilo LMS database and files before making any changes
- 2. Download Chamilo LMS version 1.11.38 (or later 1.x version) OR version 2.0.0-RC.3 (or later 2.x version) from the official repository at https://github.com/chamilo/chamilo-lms/releases
- 3. Replace the existing installation files with the new version, preserving configuration and user data
- 4. Run any database migration scripts included in the upgrade (check documentation for ./public/main/install/ or similar upgrade commands)
- 5. Verify the upgrade was successful by logging in and checking the version number in the admin panel
- 6. Test that the gradebook functionality works correctly and that the vulnerability is remediated by attempting to access another teacher's gradebook results (should be denied)
