CVE-2026-34520

Опубликовано: 01 апр. 2026
Источник: redhat
CVSS3: 3.7

Описание

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, the C parser (the default for most installs) accepted null bytes and control characters in response headers. This issue has been patched in version 3.13.4.

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. The default C parser incorrectly processed null bytes and control characters present in HTTP response headers. This vulnerability could allow a remote attacker to inject malicious data into these headers, potentially leading to unexpected application behavior or security bypasses.

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.
