CVE-2026-34993

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.

Summary
  • (es) AIOHTTP es un framework de cliente/servidor HTTP asíncrono para asyncio y Python. Antes de la versión 3.14.0, el uso de 'CookieJar.load()' con entrada no confiable puede permitir la ejecución de código arbitrario. La mayoría de las aplicaciones que usan esta función lo harán con los propios datos del usuario, por lo que es poco probable que esto afecte a muchas aplicaciones. La versión 3.14.0 corrige el problema. Si una aplicación permite que se carguen archivos controlados por el atacante, una solución alternativa en versiones anteriores sería sanitizar los archivos antes de cargarlos.
