Moodle allows attackers to trigger the generation of arbitrary messages

Check your stack

The advisory, in context

The LTI module in Moodle through 2.4.11, 2.5.x before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3 does not properly restrict the parameters used in a return URL, which allows remote attackers to trigger the generation of arbitrary messages via a modified URL, related to mod/lti/locallib.php and mod/lti/return.php.

Affected packages

Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
