CVE-2025-69227

AIOHTTP vulnerable to DoS when bypassing asserts

Impact

### Summary When assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. ### Impact If optimisations are enabled (`-O` or `PYTHONOPTIMIZE=1`), and the application includes a handler that uses the `Request.post()` method, then an attacker may be able to execute a DoS attack with a specially crafted message. ------ Patch: https://github.com/aio-libs/aiohttp/commit/bc1319ec3cbff9438a758951a30907b072561259
