Linux Distros Unpatched Vulnerability : CVE-2026-59881

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the WebSocket client accepts and decompresses frames with the...

Python Library aiohttp < 3.14.1 Multiple Vulnerabilities

The version of the aiohttp Python library installed on the remote host is prior to 3.14.1. It is, therefore, affected by multiple vulnerabilities: - 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...

CVE-2026-54274

A flaw was found in aiohttp, an asynchronous HTTP client/server framework. An attacker can exploit this vulnerability by sending large, incomplete websocket frame payloads. This can bypass normal memory usage limits, potentially leading to a Denial of Service DoS where the affected system becomes...

PYSEC-2026-2106

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-2026-54280

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-2026-54280

CVE-2026-54280 affects the AIOHTTP project (async HTTP client/server for asyncio/Python). Before version 3.14.1, payload resources may not be closed correctly if a client disconnects mid-write, allowing temporary resource starvation when a payload uses a limited resource (e.g., open files). The i...

EUVD-2026-38312

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-2026-54275 AIOHTTP: TLS Server Hostname Override Is Ignored When Reusing HTTPS Connections

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...

EUVD-2026-38311

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

CVE-2026-54279 affects the aiohttp library (Python asyncio framework). Prior to version 3.14.1, host-only cookies saved with CookieJar.save() and later restored with CookieJar.load() may lose their host-only status, effectively becoming domain cookies. The issue is fixed in aiohttp 3.14.1. Affect...

CVE-2026-50269

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...
