This vulnerability allows attackers to obscure the specific applet being executed. By exploiting opaque multi-call binaries, an attacker can bypass exec approval mechanisms, thereby weakening the risk classification associated with potentially unsafe applet invocations. This can lead to unauthorized command execution and privilege escalation within the affected system.
