I've managed to get around latest cloudflare verify box @ilike2burnthing
update chrome to latest version (136 as of this post) (used google-chrome-stable_current_amd64.deb)
page load:

 def access_page(driver: WebDriver, url: str) -> None:
     driver.get("https://dereferer.me/?"+url)
-    driver.start_session()
-    driver.start_session()
+    time.sleep(5) # wait for dereferer to redirect

turn off webtools:

#    options.add_argument("--auto-open-devtools-for-tabs")

click verify button:

+from selenium.webdriver.common.keys import Keys
+ # probably click on body or div containing shadowroot here
+        actions = ActionChains(driver)
+        actions.pause(1).send_keys(Keys.TAB).pause(1).send_keys(Keys.SPACE).perform()

this works both on docker headless and linux gui & headless (using --headless , didnt have xvfb) as of writing this post.
instead of accessing closed shadowroot and sending click, this simply uses tab key to select checkbox and press it.
dereferer and devtools is for anti detection. of course that's just a lazy proof of concept and needs proper integration, sleep/wait times, "local dereferer" etc

Thanks. More work probably needs done, feel free to submit PRs.

Working in Windows - binaries, from source, and build.

Docker not so much :/ would appreciate if you could have a look at it.

EDIT: Docker appears to be working for others, so may be me.

couldn't see it on mobile, but was "dereferer" added? I found it was an important thing to do, otherwise after clicking it wouldn't verify and get stuck in a loop. I think it can be done locally as well
also I had used Google chrome instead of chromium if that's relevant

Dereferer wasn't used, as in my testing it didn't seem to be needed, though now it's not working in Docker for me (but is for others, so 🤷).

If you have free time in the future, we're always open to improvements, so if something like that could be done locally, that'd be great.

Chrome is used when running from source, whereas Chromium is used with the binaries and in the Docker container. Shouldn't make any difference though if they're the same version (currently Docker pulls from the stable Debian source list, and so it's only v120, so that may be where the issue is arising, not sure).

that could be, I used the latest version from Google
but I found out at least in Linux gui and headless docker, dereferer was necessary otherwise it was stuck on a loop
I tried old javascript:... link but it said url wasn't supported, so i just tested with dereferer[.]me. I saw something like data:text/html; in source, that can be used to simply do a window.location=".." or whatever dereferer[.]me does
