EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.8%, top 47% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Apache Wicket 6.x before 6.25.0, 7.x before 7.5.0, and 8.0.0-M1 provide a CSRF prevention measure that fails to discover some cross origin requests. The mitigation is to not only check the Origin HTTP header, but also take the Referer HTTP header into account when no Origin was provided. Furthermore, not all Wicket server side targets were subjected to the CSRF check. This was also fixed.
