Use safe serialization standards such as or Protocol Buffers .
Configure frontend reverse proxies (like Nginx or Apache) to reject ambiguous requests containing conflicting Content-Length and Transfer-Encoding headers. 3. Avoid Unsafe Deserialization wsgiserver 02 cpython 3104 exploit
Move to the latest stable version of Python (e.g., Python 3.11+ or updated 3.10 micro-versions) that patches underlying interpreter bugs. Use safe serialization standards such as or Protocol Buffers
Older WSGI server iterations occasionally mishandle URL decoding. wsgiserver 02 cpython 3104 exploit
Securing your environment against these threats requires updating the stack and applying defense-in-depth strategies. 1. Upgrade Python and WSGI Software
The most effective defense is to eliminate the vulnerable components entirely:
WSGIServer 02 fails to strictly validate the Content-Length and Transfer-Encoding headers.
