+Subject: [PATCH] [3.8] gh-102153: Start stripping C0 control and space chars
+ in `urlsplit` (GH-102508) (GH-104575) (GH-104592) (#104593)
+
+gh-102153: Start stripping C0 control and space chars in `urlsplit` (GH-102508)
+
+`urllib.parse.urlsplit` has already been respecting the WHATWG spec a bit GH-25595.
+
+This adds more sanitizing to respect the "Remove any leading C0 control or space from input" [rule](https://url.spec.whatwg.org/GH-url-parsing:~:text=Remove%20any%20leading%20and%20trailing%20C0%20control%20or%20space%20from%20input.) in response to [CVE-2023-24329](https://nvd.nist.gov/vuln/detail/CVE-2023-24329).
+
+I simplified the docs by eliding the state of the world explanatory
+paragraph in this security release only backport.  (people will see
+that in the mainline /3/ docs)
+

++URL parsing security
++--------------------
++
++The :func:`urlsplit` and :func:`urlparse` APIs do not perform **validation** of
++inputs.  They may not raise errors on inputs that other applications consider
++invalid.  They may also succeed on some inputs that might not be considered
++URLs elsewhere.  Their purpose is for practical functionality rather than
++purity.
++
++Instead of raising an exception on unusual input, they may instead return some
++component parts as empty strings. Or components may contain more than perhaps
++they should.
++
++We recommend that users of these APIs where the values may be used anywhere
++with security implications code defensively. Do some verification within your
++code before trusting a returned component part.  Does that ``scheme`` make
++sense?  Is that a sensible ``path``?  Is there anything strange about that
++``hostname``?  etc.
