Timeline

2026-01-05	first spoke of it: aiohttp: aiohttp: Denial of Service via specially crafted POST request	Red Hat
2026-01-06	first spoke of it: 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.	NVD

What it is to other things

affects	aiohttp/aiohttp NVD
made_by	aiohttp NVD

In words only, so not counted until a person confirms one:

made_by	`aio_libs` NVD says “aio-libs”
affects	`aio_libs/aiohttp` NVD says “aio-libs · aiohttp”

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. zetlyn/cve-nvd · 2026-01-06	automatable yes cvss 7.5 cvss4 6.6 cvss4_vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X cvss_vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H cwe CWE-835 exploitation none product aiohttp severity HIGH status Analyzed technical_impact partial vendor aio-libs	source
