WWBN AVideo is an open source video platform. In versions up to and including 29.0, an incomplete fix for AVideo's test.php adds escapeshellarg for wget but leaves the file_get_contents and curl code paths unsanitized, and the URL validation regex /^http/ accepts strings like httpevil[.]com. Commit 78bccae74634ead68aa6528d631c9ec4fd7aa536 contains an updated fix.
