Moodle allows attackers to extract archives to arbitrary directories

Check your stack

The advisory, in context

mdeploy.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 allows remote authenticated users to bypass intended access restrictions and extract archives to arbitrary directories via a crafted dataroot value.

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.
