Exploitation requires a crafted session recording and an administrator to actively replay it; it provides no code execution or privilege escalation and at most causes display manipulation or limited information disclosure during log viewing. Given these narrow trigger conditions and no integrity or availability impact, it is reasonable to treat this as low priority for managed enterprise servers and VMs.",
