CVE-2025-69224
AIOHTTP's unicode processing of header values could cause parsing discrepancies
Impact
### Summary The Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. ### Impact If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. ------ Patch: https://github.com/aio-libs/aiohttp/commit/32677f2adfd907420c078dda6b79225c6f4ebce0
