Hi, The following vulnerability was published for python-aiohttp. CVE-2026-47265[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
