CVE-2025-50187
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 is a learning management system. Prior to version 1.11.28, parameter from SOAP request is evaluated without filtering which leads to Remote Code Execution. This issue has been patched in version 1.11.28.
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 analysis · high confidenceChamilo LMS versions prior to 1.11.28 contain a Remote Code Execution vulnerability where SOAP request parameters are evaluated without proper filtering, allowing unauthenticated attackers to execute arbitrary code on the server.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the installed Chamilo versionCheck the version.php file in the main directory, the admin panel 'About' page, or the CHANGELOG.txt file. Look for a version constant or displayed version number.Affected if The version number is lower than 1.11.28 (e.g., 1.11.27, 1.11.26, etc.)
-
Confirm PHP SOAP extension is loadedRun 'php -m' or check phpinfo() for the 'soap' module. Alternatively, look for 'extension=soap' in the active php.ini file.Affected if The SOAP extension is loaded and enabled in PHP configuration.
-
Identify accessible SOAP endpointsSearch the application source for SOAP service files (e.g., files containing 'SoapServer' or 'soap.wsdl'). Check the web server configuration for routes exposing /soap/ or similar paths.Affected if SOAP endpoints are publicly accessible or accessible to authenticated users.
-
Verify SOAP request handling in the codebaseReview the SOAP service implementation code for eval(), call_user_func(), or similar dynamic code execution functions that process request parameters.Affected if The SOAP handler processes input parameters without proper sanitization or uses unsafe dynamic evaluation.
The environment is affected if Chamilo version is below 1.11.28 AND the SOAP extension is enabled AND SOAP endpoints are accessible to the attacker.

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 · scoped1.11.28
Upgrade to Chamilo version 1.11.28 or later. If immediate upgrade is not possible, disable or restrict access to SOAP endpoints as a temporary measure.
1.11.28
- Backup the current Chamilo LMS installation and database before upgrading
- Download Chamilo LMS version 1.11.28 from the official repository (github.com/chamilo/chamilo-lms)
- Replace existing files with the new version 1.11.28 files
- Run any database migration scripts included in the upgrade package
- Clear any cached data to ensure new code is loaded
- Verify the upgrade by logging into the admin panel
- Confirm SOAP functionality works correctly with the patched version
