CVE
GHSA-jj3x-wxrx-4x23
AIOHTTP vulnerable to DoS when bypassing asserts
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.
