| CVE-2026-34520 | Cri | 0.52 | 9.1 | 0.00 | Apr 1, 2026 | 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. | |
| CVE-2026-34516 | Hig | 0.42 | 7.5 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, a response with an excessive number of multipart headers may be allowed to use more memory than intended, potentially allowing a DoS vulnerability. This issue has been patched in version 3.13.4. | |
| CVE-2026-34515 | Hig | 0.42 | 7.5 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, on Windows the static resource handler may expose information about a NTLMv2 remote path. This issue has been patched in version 3.13.4. | |
| CVE-2026-34513 | Hig | 0.42 | 7.5 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, an unbounded DNS cache could result in excessive memory usage possibly resulting in a DoS situation. This issue has been patched in version 3.13.4. | |
| CVE-2026-22815 | Hig | 0.42 | 7.5 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, insufficient restrictions in header/trailer handling could cause uncapped memory usage. This issue has been patched in version 3.13.4. | |
| CVE-2026-34525 | Med | 0.27 | 5.3 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, multiple Host headers were allowed in aiohttp. This issue has been patched in version 3.13.4. | |
| CVE-2026-34519 | Med | 0.27 | 5.3 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, an attacker who controls the reason parameter when creating a Response may be able to inject extra headers or similar exploits. This issue has been patched in version 3.13.4. | |
| CVE-2026-34518 | Med | 0.27 | 5.3 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, when following redirects to a different origin, aiohttp drops the Authorization header, but retains the Cookie and Proxy-Authorization headers. This issue has been patched in version 3.13.4. | |
| CVE-2026-34517 | Med | 0.27 | 5.3 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, for some multipart form fields, aiohttp read the entire field into memory before checking client_max_size. This issue has been patched in version 3.13.4. | |
| CVE-2026-34514 | Med | 0.27 | 5.3 | 0.00 | Apr 1, 2026 | AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, an attacker who controls the content_type parameter in aiohttp could use this to inject extra headers or similar exploits. This issue has been patched in version 3.13.4. |
