description

Apache Wicket applications using a mounted FileUploadToResourceField may accept untrusted upload metadata through its callback. An attacker able to reach the page can cause excessive heap allocation and potentially disrupt the JVM when the application calls UploadInfo#get(); deployments that deny the field's ENABLE action reduce exposure.

mitigation

Upgrade Apache Wicket 9.x to 9.25.0 or 10.x to 10.12.0. Until upgraded, disable or restrict access to FileUploadToResourceField callbacks, including by denying the field's ENABLE action where feasible.
