A weakness has been identified in givanz Vvvebjs up to 2.0.5. The affected element is an unknown function of the file upload.php of the component File Upload Endpoint. This manipulation of the argument uploadAllowExtensions causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. Patch name: 8cac22cff99b8bc701c408aa8e887fa702755336. Applying a patch is the recommended action to fix this issue.
