aioHTTP < 3.14.0 Multiple Vulnerabilities

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...

CVE-2026-34993

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. An attacker could exploit this vulnerability by providing untrusted input to the CookieJar.load function. This could potentially lead to arbitrary code execution, allowing the attacker to run malicio...

OESA-2026-2563 python-aiohttp security update

Async http client/server framework asyncio. Security Fixes: Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications.CVE-2026-34993 If a developer uses the cookies parameter on a per-request basis then sensitive data might be...

SUSE CVE-2026-47265

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 ...

CVE-2026-47265

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. This vulnerability allows a remote attacker to potentially gain access to sensitive information. When a developer uses the cookies parameter on a per-request basis, cookies are sent after following a...

GHSA-HG6J-4RV6-33PG AIOHTTP is vulnerable to cross-origin redirect with per-request cookies

Summary Cookies set with the cookies parameter on requests are sent after following a cross-origin redirect. Impact 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. Workaround If unable to...

Origin Validation Error

Overview Affected versions of this package are vulnerable to Origin Validation Error via the cookies parameter, which is processed by connectandsendrequest in client.py. An attacker who can control a redirect on a request that passes cookies on a per-request basis can expose data from those...

AIOHTTP is vulnerable to cross-origin redirect with per-request cookies

Summary Cookies set with the cookies parameter on requests are sent after following a cross-origin redirect. Impact 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. Workaround If unable to...

GHSA-JG22-MG44-37J8 AIOHTTP is Vulnerable to Deserialization of Untrusted Data

Summary Using CookieJar.load with untrusted input may allow arbitrary code execution. Impact Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. Workaround If an application does allow attacker controlled files to be...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the CookieJar.load function. A user who convinces another user to load a malicious serialized object can cause the execution of arbitrary code. Details Serialization is a process of converting an...
