CVE-2022-23654: Improper write access check in Requarks/wiki
Wiki.js is a wiki app built on Node.js. In affected versions an authenticated user with write access on a restricted set of paths can update a page outside the allowed paths by specifying a different target page ID while keeping the path intact. The access control incorrectly check the path access against the user-provided values instead of the actual path associated to the page ID. Commit https://github.com/Requarks/wiki/commit/411802ec2f654bb5ed1126c307575b81e2361c6b fixes this vulnerability by checking access control on the path associated with the page ID instead of the user-provided value. When the path is different than the current value, a second access control check is then performed on the user-provided path before the move operation.
