Is there a pithy phrase covering accidental "in-band signaling"-style vulnerabilities? Think HTTP request smuggling and packet-in-packet attacks (this is regarding the recent Tarmageddon).
There's "format injection" but the typical cases for that are more like "format string injection" / escaping vulnerabilities.
@bascule polyglot smuggling?
5 years ago I made a honeypot TCP server supporting ssh, http, https and Minecraft at the same time, that decides which protocol to use from first few header bytes. So it was kinda reverse polyglot.
I think some HTTP proxies do scan the CONNECT streams for structured data, so they might suffer from "false synchronization" just like frame transmissions in telecommunications.
