|---|---|---|---|---|---|
| CVE-2026-120306 | 9.9 critical | — | beam-cloud, beta9 worker | Beta9 turns each shell command in a tenant image definition into a Dockerfile RUN line and executes it with Buildah on the build worker. The worker image sets BUILDAH_ISOLATION=chroot, and no buildah invocation passes --isolation, so the step only changes its filesystem root. It keeps the worker pod's PID, network, IPC, and user namespaces, runs as uid 0, and holds CAP_DAC_OVERRIDE. PID 1 in that procfs is the worker entrypoint, so /proc/1/root is the worker container's filesystem and is writable. That filesystem contains the runc, buildah, and runsc binaries the worker uses to start tenant containers, the worker's Kubernetes service account token, and the host directories mounted into the pod. Worker pods are privileged. Clip v2 layered builds are the default, so a tenant with a workspace token reaches this by submitting one image build. The read-only proof confirmed the shared namespaces, CAP_DAC_OVERRIDE, and that the worker's runc binary is visible at /proc/1/root. Fixed in worker 0.1.756: Buildah RUN steps, including the WORKDIR mkdir, use OCI isolation with private PID, IPC, and network namespaces, and tenant ARG values are passed only into the build container. | 22 h ago |
| CVE-2026-82559 | 2.3 low | — | apache software foundation, apache wicket | Insufficient session expiration in Apache Wicket. org.apache.wicket.protocol.ws.WebSocketSettings#newWebSocketRequest() wraps the WebSocket upgrade request in an org.apache.wicket.protocol.ws.api.ServletRequestCopy, which is kept for the life of the connection and used to build the request for every frame that arrives on it. Copying the request is deliberate and is documented as such, because the container recycles the upgrade request once the handshake is over. The container session is copied along with it, into an org.apache.wicket.protocol.ws.api.HttpSessionCopy holding the session attributes as they stood when the connection was opened. That second copy is not necessary, because a session, unlike a request, is not discarded at the end of a request. Every frame afterwards resolves its Wicket session through ISessionStore#lookup(), which reads it out of the copy, so the connection is detached from the live container session for as long as it stays open. Ending the session through the container therefore does not end the connection. After an idle timeout, an HttpSession#invalidate() call made from a filter or from a security framework, a container-managed logout, or a session replacement, the connection goes on resolving the org.apache.wicket.Session instance that existed when it was opened, together with that session's attributes and, for applications built on wicket-auth-roles, the signed-in state held on that same instance, so an authorization decision taken inside a WebSocket callback is taken against an identity that has already been revoked. The copy is also what the connection writes through: a Session#invalidateNow() issued from inside a WebSocket callback invalidates the copy and leaves the container session valid, and session attributes set over the connection are written to the copy rather than to the session. An application is affected where it uses Wicket's native WebSocket support on pages or shared resources that require an authenticated session, and where sessions are ended by the container rather than by Wicket. Session#invalidateNow(), and AuthenticatedWebSession#invalidate() and #signOut() which call it, remain effective for a WebSocketBehavior on a page: they clear the page manager, and the connection can then no longer resolve the page it was opened for. A WebSocketResource is not limited in that way, because a frame naming a resource is served against a throwaway page and never consults the page manager, so such a connection outlives Wicket's own sign-out as well. Some containers close WebSocket connections themselves when the HTTP session they were opened under is destroyed, in which case the connection ends regardless; that is a property of the container rather than of Wicket. Applications that do not use the native WebSocket support are not affected. 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 6.0.0 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. | 13 h ago |
