Affected: Homebrew: aider

### Summary A request can be crafted in such a way that an aiohttp server's memory fills up uncontrollably during processing.

### Impact 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.

Affected: CleanStart: airflow-2

Multiple security vulnerabilities affect the airflow-2 package. These issues are resolved in later releases. See references for individual vulnerability details.

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.

Affected: PyPI: aiohttp

Async http client/server framework (asyncio). Security Fix(es):

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below contain parser logic which allows non-ASCII decimals to be present in the Range header. There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. This issue is fixed in version 3.13.3.(CVE-2025-69225)

aiohttp contains a denial-of-service vulnerability when bypassing asserts, allowing attackers to bypass assertion checks through specific methods leading to service unavailability.(CVE-2025-69227)

aiohttp contains a vulnerability when processing large payloads. An attacker can craft large requests to exhaust server resources, leading to denial of service.(CVE-2025-69228)

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of small chunks. If an application makes use of the `request.read()` method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g., 1 second) while processing the request. This could potentially lead to a Denial of Service (DoS) as the server would be unable to handle other requests during that time.(CVE-2025-69229)
