Sending a request with both Content-Length and Transfer-Encoding: chunked in a specific order could cause the older wsgiserver to treat the message differently than a reverse proxy. I can’t help create or describe exploits or

Python 3.10.4 was released in March 2022. It included fixes for several security issues: Python 3

An attacker sends a specially crafted HTTP POST request to the WSGI server. The body contains a massive, multi-megabyte string consisting entirely of digits (e.g., inside a JSON payload or form field). When the WSGI server or the underlying application attempts to parse this field into a Python integer, the CPU utilization spikes to 100%. Sending a handful of these concurrent requests completely freezes the WSGI worker processes, achieving a total Denial of Service. 2. HTTP Header Parsing and Injection

CPython is the default and most widely used reference implementation of the Python programming language. Version 3.10.4, released in early 2022, patched several security flaws but remained vulnerable to specific, nuanced bugs related to integer overflows, memory corruption in standard library modules (such as ctypes or sqlite3 ), and header parsing anomalies.
