  1. CVE-2026-87114 7.1 Élevée

    Red Hat OpenShift Container Platform 4.19 · Red Hat OpenShift Container Platform 4.20 · Red Hat OpenShift Container Platform 4.21 · Red Hat OpenShift Container Platform 4.22

    A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.

  2. CVE-2026-75887 7.5 Élevée

    Red Hat OpenShift Container Platform 4.12 · Red Hat OpenShift Container Platform 4.13 · Red Hat OpenShift Container Platform 4.14 · Red Hat OpenShift Container Platform 4.15

    A flaw was found in the OpenShift console. An unauthenticated attacker can exploit a path traversal vulnerability by manipulating the `lng` and `ns` query parameters in the `/locales/resource.json` endpoint. This allows the attacker to read sensitive `*.json` files from the pod filesystem, including plugin manifests and configuration files. Furthermore, this flaw can enable path traversal against registered dynamic-plugin backends.

  3. CVE-2026-75886 7.2 Élevée

    Red Hat OpenShift Container Platform 4.17 · Red Hat OpenShift Container Platform 4.18 · Red Hat OpenShift Container Platform 4.19 · Red Hat OpenShift Container Platform 4.20

    A flaw was found in openshift/console. An unauthenticated remote attacker can exploit a misconfiguration in the CatalogdHandler, which lacks proper authentication, and the forwarding of the `openshift-session-token` cookie. This allows the attacker to send requests to the in-cluster catalogd service, leading to the disclosure of the internal operator-catalog index and providing a relay into the openshift-catalogd namespace.

  4. CVE-2026-75885 9.3 Critique

    Red Hat OpenShift Container Platform 4.12 · Red Hat OpenShift Container Platform 4.13 · Red Hat OpenShift Container Platform 4.14 · Red Hat OpenShift Container Platform 4.15

    A flaw was found in the OpenShift console. Unauthenticated access to the `/api/devfile/` and `/api/devfile/samples/` endpoints allows a remote attacker to send crafted devfile payloads. This can lead to Server-Side Request Forgery (SSRF), where the console pod makes requests to internal services and reflects partial responses to the attacker. Additionally, by sending repeated large requests without a specified content length, an attacker can cause unbounded memory growth, leading to a Denial of Service (DoS).

  5. CVE-2026-49329 7.5 Élevée

    Red Hat OpenShift Container Platform 4.14 · Red Hat OpenShift Container Platform 4.15 · Red Hat OpenShift Container Platform 4.18 · Red Hat OpenShift Container Platform 4.19

    A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.
