Medium (6.5) in apache wicket. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in org.apache.wicket:wicket 10.0.0, 9.17.0.
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.
