CVE-2026-82115: Apache Wicket: The configured authorization strategy is not applied to a shared WebSocketResource

Noroxi assessment

Priority: Monitor (action score 25/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache Wicket 8.20.0.

Low priority for now. Upgrade to Apache Software Foundation Apache Wicket 8.20.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Missing authorization in Apache Wicket. org.apache.wicket.protocol.ws.api.WebSocketMessageBroadcastHandler, the request handler Wicket's native WebSocket support uses to deliver an incoming frame, resolves the shared resource named by the client's handshake parameter and calls WebSocketResource#onPayload() on it directly, without consulting IAuthorizationStrategy#isResourceAuthorized(). That method has a single enforcement point in the framework, org.apache.wicket.request.handler.resource.ResourceRequestHandler, which the WebSocket transport does not pass through, and WebSocketResource#respond() is final and empty. No route to a WebSocketResource therefore asks the configured authorization strategy whether the caller may use it, and an @AuthorizeResource annotation on such a class has no effect. A caller needs a bound Wicket session and the name of the resource. The name is not a secret: Wicket writes it into the page that opens the connection. No page of the application is otherwise involved, because a request naming a resource is served with a throwaway page. All of the resource's callbacks are reached this way, including onConnect() and both onMessage() overloads, and what a callback pushes back through WebSocketRequestHandler goes to the caller's own connection. An application is affected where it registers a WebSocketResource as a shared resource and relies on the authorization strategy to restrict it. What the caller gains is whatever that resource's callbacks do with a text or binary message of the caller's choosing. The connection is registered under the caller's own session, so it gives no access to another user's connection. As a workaround, reject unauthorized connections with an IWebSocketConnectionFilter registered through WebSocketSettings#setConnectionFilter(), or repeat the authorization check at the start of each callback. This issue affects Apache Wicket: from 8.0.0 through 8.19.0, from 9.0.0 through 9.24.0, from 10.0.0 through 10.11.0. Older, unsupported releases from 7.0.0 onwards are also affected. Users are recommended to upgrade to version 8.20.0, 9.25.0 or 10.12.0, which fix the issue.
