CVE-2026-54280: Improper Resource Shutdown or Release

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, payload resources are not closed correctly when a client disconnects in the middle of a write. If a payload is using an open file or similar limited resource, then an attacker may be able to cause...

CVE-2026-54275: Improper Validation of Certificate with Host Mismatch

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, the serverhostname TLS SNI check can be bypassed when an existing connection is reused. If an application makes multiple requests to the same domain, but with different per-request serverhostname...

CVE-2026-50269: Improper Neutralization of CRLF Sequences

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.0, attacker-controlled input included into multipart/payload headers can be used to modify a request to inject additional headers or similar. In the unlikely situation that an application is passing...

CVE-2026-54277: Allocation of Resources Without Limits or Throttling

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, it is possible to bypass the maxlinesize check in parts of an HTTP request in the C parser. If using the optimised C parser the default in pre-built wheels, then an attacker may be able to send...

CVE-2026-54279: Improper Initialization

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, host-only cookies that are saved with CookieJar.save and then restored later with CookieJar.load lose their host-only status. This vulnerability is fixed in 3.14.1...

CVE-2026-54273: Allocation of Resources Without Limits or Throttling

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This...
