[Web-SIG] ANNOUNCE: WSGI XSS Prevention Middleware

[Richard Moore]

Hi,

I've just written a python WSGI middleware class to mitigate
XSS flaws, it's released under the python license. I've
attached the docs below.

Cheers

Rich.

WSGI Middleware class that prevents cross-site scripting flaws
in WSGI applications being exploited. Potentially malicious GET
and POST variables are checked for, and if found, a 403
Forbidden response is sent to the client.

Note that this class can false positive on input such as XML
or passwords containing the '<' character, so it is not useful
in all contexts. In addition, you should note that this
middleware is not a replacement for properly validating
input and quoting output.

This class can be downloaded from:
