reg.php in Allen Disk 1.6 doesn't check if isset($_SESSION['captcha']['code'])==1, which makes it possible to bypass the CAPTCHA via an empty $_POST['captcha'].
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
