Denial Of Service (DoS)

aiohttp is vulnerable to a Denial of Service DoS. The vulnerability is due to improper handling of crafted requests in the Request.post method, which allows an attacker to exhaust server memory and freeze the AIOHTTP server during request processing...

CVE-2025-69226

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. An attacker can exploit a vulnerability in the path normalization logic for static files to determine if specific absolute path components exist on the server. This information disclosure is possible if the...

CVE-2025-69224

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. A remote attacker could exploit this vulnerability by sending requests containing non-ASCII characters to the Python HTTP parser. This could lead to a request smuggling attack, allowing the attacker to bypass...
