CVE-2018-14334
manager/editor/upload.php in joyplus-cms 1.6.0 allows arbitrary file upload because detection of a prohibited file extension simply sets the $errm value, and does not otherwise alter the flow of control.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
