Summary

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-r94f-hx44-8jqf. This link is maintained to preserve external references. ### Original Description Grav CMS before 2.0.13 contains a remote code execution vulnerability in the Flex Objects plugin settings validation that allows authenticated users to execute arbitrary code by uploading a ZIP file containing PHP code. Attackers can bypass routine name validation by using array notation instead of string notation, call the unZip routine with a malicious archive, and write PHP files to the web root for execution.
