CVE-2023-50784 (https://forums.unrealircd.org/viewtopic.php?t=9340):

A buffer overflow in websockets in UnrealIRCd 6.1.0 through 6.1.3 before 6.1.4 allows an unauthenticated remote attacker to crash the server by sending an oversized packet (if a websocket port is open). Remote code execution might be possible on some uncommon, older platforms.
