CVE-2026-45365: Fastapi Internal Auth Bypass Flag As Query Param
FastAPI route handler `$FN` declares `$PARAM` as a plain primitive-typed function parameter. Because the parameter is a `bool`/`Optional[bool]` and is not wrapped in `Body(...)`, `Header(...)`, `Cookie(...)`, or `Depends(...)`, FastAPI binds it to the HTTP query string. An external caller can therefore append `?$PARAM=true` to the request URL and flip an int
