aioHTTP < 3.14.0 Multiple Vulnerabilities

high Nessus Plugin ID 320552

Synopsis

A Python library installed on the remote host is affected by multiple vulnerabilities.

Description

The version of aioHTTP installed on the remote host is prior to 3.14.0. It is, therefore, affected by multiple vulnerabilities:

 - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, using CookieJar.load() with untrusted input may allow arbitrary code execution. Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications.
 Version 3.14.0 patches the issue. If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitize the files before loading. (CVE-2026-34993)

 - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, cookies set with the cookies parameter on requests are sent after following a cross-origin redirect. If a developer uses the cookies parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade, using a Cookie header in the headers parameter is not vulnerable. (CVE-2026-47265)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to aioHTTP version 3.14.0 or later.
