description

Apache Wicket 8.0.0 through 8.19.0 can render attacker-influenced ExternalLink URLs into browser-executed event handlers. An attacker may execute script in the application's origin when an application uses ExternalLink with a non-link element or popup settings and a user activates the affected element.

mitigation

Upgrade Apache Wicket to version 8.20.0. Move unsupported 7.x or older deployments to a supported release.
