CVE-2025-69227

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. A remote attacker could exploit this vulnerability by sending a specially crafted POST request to an application using the Request.post() method, provided that Python optimizations are enabled. This could lead to an infinite loop, resulting in a Denial of Service (DoS) attack, making the affected application unavailable.

CVE-2025-69228

A flaw was found in aiohttp. A remote attacker can craft a malicious request that, when processed by an aiohttp server using the `Request.post()` method, causes the server's memory to fill uncontrollably. This can lead to a Denial of Service (DoS) by freezing the server, making it unavailable to legitimate users.

CVE-2026-69244

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability involves an out-of-bounds heap read in the C response parser when processing malformed HTTP responses. An attacker operating a malicious server, or even an accidental malformed response, could exploit this to trigger a Denial of Service (DoS) in the client application, making it unavailable.

CVE-2025-69227 (GCVE-0-2025-69227)

Vulnerability from cvelistv5 – Published: 2026-01-05 23:19 – Updated: 2026-01-06 19:02

Title

AIOHTTP vulnerable to DoS when bypassing asserts

Summary

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

6.6 (Medium)

CVE-2025-69228 (GCVE-0-2025-69228)

Vulnerability from cvelistv5 – Published: 2026-01-05 23:30 – Updated: 2026-01-06 19:02

Title

AIOHTTP vulnerable to denial of service through large payloads

Summary

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a request to be crafted in such a way that an AIOHTTP server's memory fills up uncontrollably during processing. If an application includes a handler that uses the Request.post() method, an attacker may be able to freeze the server by exhausting the memory. This issue is fixed in version 3.13.3.

Severity

6.6 (Medium)

CVE-2026-69244 (GCVE-0-2026-69244)

Vulnerability from cvelistv5 – Published: 2026-08-03 20:50 – Updated: 2026-08-04 14:13

Title

AIOHTTP: Out-of-bounds heap read in C HTTP response parser error path (malformed chunked response)

Summary

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp error-position pointer was used to build a snippet for malformed chunked responses and malformed request or response bytes at the buffer end. This issue is fixed in version 3.14.3.

Severity

7.1 (High)
