CVE-2026-54280 AIOHTTP: Payload Response Resources Are Not Closed After Mid-Body Disconnect
PublishedLowCVSS 1.7 EPSS 0.46%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...

PublishedMediumCVSS 6.6 EPSS 0.49%AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, during cleanup it is possible for a compressed request body to be decompressed into memory in one chunk. An attacker may be able to send a compressed payload in specific situations th...

PublishedLowCVSS 2.7 EPSS 0.47%AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, the server_hostname 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 s...

MediumCVSS 6.6 EPSS 0.54%
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, if an attacker sends large incomplete websocket frame payloads, it may be possible to bypass the usual size limits on memory use. This vulnerability is fixed in 3.14.1.

CVE-2026-54279 AIOHTTP: Host-Only Cookies Become Domain Cookies After CookieJar Persistence
PublishedLowCVSS 1.3 EPSS 0.49%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.
