SeaCMS 6.61 allows remote attackers to execute arbitrary code because parseIf() in include/main.class.php does not block use of $GLOBALS.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
