feature: add nonceless/tokenless CSRF protection Add tokenless CSRF protection following: https://words.filippo.io/csrf/ Must be enabled using use_tokenless_csrf_protection in config.ini. By default it's off. If enabled the older csrf_* settings are ignored. The allowed_api_origins setting is still used for Origin comparisons. This should also improve performance as a nonce isn't required so generating random nonce and saving it to the otks database is eliminated. doc/admin_guide.txt, doc/reference.txt doc/upgrading.txt doc updates. roundup/configuration.py add use_tokenless_csrf_protection setting. move allowed_api_origins directly after use_tokenless_csrf_protection and before the older csrf_* settings. It's used by both of them. Rewrite description of allowed_api_origins as its applied to all URLs with tokenless protection, not just API URLs. roundup/anypy/urllib_.py import urlsplit, it is used in new code. urlparse() is less efficient and splits params out of the path component. Since Roundup doesn't require that params be split from the path. I expect future patch will replace urlparse() with urlsplit() globally and not need urlparse(). roundup/cgi/client.py add handle_csrf_tokenless() and call from handle_csrf() if use_tokenless_csrf_protection is enabled. refactor code that expires csrf tokens when used with the wrong methods (i.e. GET) into expire_exposed_keys(). Call same from handle_csrf and handle_csrf_tokenless. Also improve logging if this happens including both Referer and Origin headers if available. Arguably we dont care about CSRF tokens exposed via GET/HEAD/OPTIONS in the tokenless case, but this cleans them up in case the admin has to switch back. At some future date we can delete all the nonce based CSRF from 2018. Update handle_csrf() docstring about calling/returning handle_csrf_tokenless() when enabled. Call expire_exposed_keys(method) if token is supplied with wrong method. roundup/cgi/templating.py disable nonce generation/save and always return "0" when use_tokenless_csrf_protection enabled.

   This file is a temporary way to post CVE notifications before
   a release.

   Document the CVE fix info in upgrading.txt. We extract the sections
   from upgrading.txt that deal with the CVE into a separate CVE.html.
   An updated docs/security.html and docs/CVE.html provide the details
   on a between release CVE announcment.

   Publishing upgrading.txt would include info on the to be released
   roundup software and wouldn't match the rest of the release docs.

   To extract the info from upgrading.txt to use in CVE.html, add a
   commented out a reference anchor in upgrading.txt. Then in CVE.txt
   we use an include directive with start-after and end-before options
   to exract the sections from upgrading.txt into CVE.html.

   The extracted section in CVE.txt gets the same anchor that is in
   upgrading.txt, but is is not commented out. This allows us to swap
   out CVE.txt and uncomment the reference in upgrading.txt. Then
   rerunning sphinx-build will make security.html point to the sections
   in upgrading.html.

   For example, in upgrading.txt add a

   .. comment: _CVE-2024-39124:

   before the section for the CVE (use the real CVE number). At the
   end of the CVE section add an end comment:

   .. comment: end of CVE include marker

   Update security.txt with a :ref: to the CVE section. E.G. a
   security.txt references look like:

     * `CVE-2024-39124`_ - :ref:`classhelpers (_generic.help.html) are
    vulnerable to an XSS attack. <CVE-2024-39124>` Requires fixing
    tracker homes.

   where <CVE-2024-39124> is the reference. The same reference anchor
   is present (commented out) in upgrading.txt. In CVE.txt you
   replicate the existing anchor and include to extract the content
   section from upgrading.txt. E.G.

   .. _CVE-2024-39124:

   .. include:: upgrading.txt
      :start-after: .. comment: _CVE-2024-39124:
      :end-before: .. comment: end of CVE

   After building the docs, install docs/security.html and
   docs/CVE.html on the web site. Reference:

       https://www.roundup-tracker.org/docs/security.html
   
   in the CVE announcement from Mitre.

   When the release is ready, replace 'comment: _CVE' with '_CVE' in
   upgrading.txt. This makes the anchors in upgrading.txt live.

   Then disable CVE.txt by removing CVE.txt from contents.txt in the
   toctree hidden section. Also add docs/CVE.txt to exclude_patterns in
   conf.py.

   No change needs to happen to security.txt as it's using a :ref: and
   we just changed the location for the ref so sphinx will get the
   links correct.

   Now build the docs and publish to the web site.
