Jenkins 2.227 and earlier, LTS 2.204.5 and earlier uses different representations of request URL paths, which allows attackers to craft URLs that allow bypassing CSRF protection of any target URL.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
