CVE-2025-69227 – AIOHTTP vulnerable to DoS when bypassing asserts

CVE ID : CVE-2025-69227

Published : Jan. 5, 2026, 11:19 p.m. | 1 hour, 7 minutes ago

Description : AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow for an infinite loop to occur when assert statements are bypassed, resulting in a DoS attack when processing a POST body. If optimizations 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. This issue is fixed in version 3.13.3.

Severity: 0.0 | NA
