CVE-2024-27439 | Apache Wicket: Possible bypass of CSRF protection

An error in the evaluation of the fetch metadata headers could allow a bypass of the CSRF protection in Apache Wicket. This issue affects Apache Wicket: from 9.1.0 through 9.16.0, and the milestone releases for the 10.0 series. Apache Wicket 8.x does not support CSRF protection via the fetch metadata headers and as such is not affected. Users are recommended to upgrade to version 9.17.0 or 10.0.0, which fixes the issue.

Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
