Weaponized quickly — attackers prioritized this vulnerability. Patch urgently.

An Authenticated Remote Code Exection (RCE) vulnerability exists in Xerte through 3.9 in website_code/php/import/fileupload.php by uploading a maliciously crafted PHP file though the project interface disguised as a language file to bypasses the upload filters. Attackers can manipulate the files destination by abusing path traversal in the 'mediapath' variable.
