CVE-2026-22815

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. Insufficient restrictions in header and trailer handling could allow a remote attacker to cause uncapped memory usage. This can lead to a Denial of Service DoS condition, making the affected web server...

CVE-2026-34517

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. A remote attacker could exploit this vulnerability by sending a specially crafted multipart form field. The framework would read the entire field into memory before enforcing size limits, potentially leading to...

CVE-2026-34525

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. This vulnerability allows a remote attacker to send multiple Host headers in a single request. This can lead to unexpected behavior, potentially bypassing security controls or causing cache poisoning, which may...

CVE-2026-34514
