Name of the Vulnerable Software and Affected Versions Media Library Assistant plugin for WordPress versions up to, and including, 3.18

Description The issue arises from missing file type validation involving the mla-inline-edit-upload-scripts AJAX action. This allows authenticated attackers with Author-level access and above to upload arbitrary files on the affected site's server, potentially making remote code execution possible.

Recommendations For versions up to, and including, 3.18, update to a version higher than 3.18 to resolve the issue. As a temporary workaround, consider restricting access to the mla-inline-edit-upload-scripts AJAX action until a patch is available.
