CVE-2010-4508
The WebSockets implementation in Mozilla Firefox 4 through 4.0 Beta 7 does not properly perform proxy upgrade negotiation, which has unspecified impact and remote attack vectors, related to an "inherent problem" with the WebSocket specification.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
