ANSI escape injection in MCP servers: Hidden from humans, visible to AI (brightsec.com)

This is a really interesting class of failure. It feels like we're going to see more cases where the "human view" and the "LLM view" of the same data diverge. Have you run into similar issues outside of MCP as well, or is this mostly specific to terminal-based tool interactions?

Every year is apparently a good year for developers to figure out how terminals have worked for decades?

Just… don’t trust inputs you don’t fully control, there’s nothing else to it.

So cat -v is no longer harmful?

Does the OSC 52 was mentioned?

May I ask, what is DAST exactly? The report doesn't seem to define it, nor does it provide a link to any definition or detail page, not even an abreviation expansion. Is that Dynamic application security testing?

ANSI bombs from the MS-DOS days are back for the modern age.
