### Impact A leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. ### Details HTTP/1.1 Chunked-Encoding bodies are formatted as a sequence of "chunks", each of which consists of: - chunk length - `\r\n` - `length` bytes of content - `\r\n` In versions of h11 up to 0.14.0, h11 instead parsed them as: - chunk length - `\r\n` - `length` bytes of content - any two bytes i.e. it did not validate that the trailing `\r\n` bytes were correct, and if you put 2 bytes of garbage there it would be accepted, instead of correctly rejecting the body as malformed. By itself this is harmless. However, suppose you have a proxy or reverse-proxy that tries to analyze HTTP requests, and your proxy has a _different_ bug in parsing Chunked-Encoding, acting as if the format is: - chunk length - `\r\n` - `length` bytes of content - more bytes of content, as many as it takes until you find a `\r\n` For ex...

### Summary An unhandled error is thrown when validating invalid connectionParams which crashes a tRPC WebSocket server. This allows any unauthenticated user to crash a tRPC 11 WebSocket server. ### Details Any tRPC 11 server with WebSocket enabled with a `createContext` method set is vulnerable. Here is an example: https://github.com/user-attachments/assets/ce1b2d32-6103-4e54-8446-51535b293b05 I have a working reproduction here if you would like to test: https://github.com/lukechilds/trpc-vuln-reproduction The connectionParams logic introduced in https://github.com/trpc/trpc/pull/5839 does not safely handle invalid connectionParams objects. During validation if the object does not match an expected shape an error will be thrown: https://github.com/trpc/trpc/blob/8cef54eaf95d8abc8484fe1d454b6620eeb57f2f/packages/server/src/unstable-core-do-not-import/http/parseConnectionParams.ts#L27-L33 This is called during WebSocket connection setup inside `createCtxPromise()` here: https://...
