CVE-2026-47265

Опубликовано: 02 июн. 2026
Источник: redhat
CVSS3: 6.5

Описание

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.

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 cross-origin redirect. An attacker who controls a redirect can exploit this to leak sensitive data.

Отчет

AIOHTTP, as utilized in Red Hat products, is susceptible to a Moderate information disclosure flaw. This vulnerability arises when the cookies parameter is used for per-request cookie handling, potentially exposing sensitive data if a cross-origin redirect is controlled by an attacker. This specific usage pattern of the library is required for exploitation.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

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.
