What is CVE-2026-82704?

The vulnerability in Apache Wicket arises from a failure in the authorization checks, allowing unauthorized listeners to be invoked under certain conditions. When an IRequestListener is triggered without a page identifier, the visibility and enabled state flags do not get updated properly. This can occur on both stateful and stateless pages, where the authorization strategy does not effectively prevent the execution of component listeners that should be restricted, potentially exposing sensitive functionality. This issue impacts versions 8.0.0 through 8.19.0, 9.0.0 through 9.24.0, and 10.0.0 through 10.11.0, urging users to upgrade to the fixed versions 8.20.0, 9.25.0, or 10.12.0.

Affected Version(s)

Apache Wicket 8.0.0 <= 8.19.0

Apache Wicket 9.0.0 <= 9.24.0

Apache Wicket 10.0.0 <= 10.11.0
