MCP 'design flaw' puts 200k servers at risk and Anthropic won't fix it (www.theregister.com)

A design flaw – or expected behavior based on a bad design choice, depending on who is telling the story – baked into Anthropic's official Model Context Protocol (MCP) puts as many as 200,000 servers at risk of complete takeover, according to security researchers.

It’s worse even than that. The server software (released by Anthropic) that lets an AI connect to a web service has a critical arbitrary remote code execution bug. So if you even let an AI connect to you, you’ve now allowed anyone to access your whole server.

There is no excuse for this other than wild incompetence.

Wait, but Mythos is the revolution in the software security world, it found 0-days in all popular OS's, including FreeBSD. I'm sure it would have found critical bugs in their own code! /s
