The multicluster engine for Kubernetes provides the foundational components that are necessary for the centralized management of multiple Kubernetes-based clusters across data centers, public clouds, and private clouds. You can use the engine to create new Red Hat OpenShift Container Platform clusters or to bring existing Kubernetes-based clusters under management by importing them. After the clusters are managed, you can use the APIs that are provided by the engine to distribute configuration based on placement policy.

A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.

This release of the Red Hat OpenShift distributed tracing platform (Tempo) provides security improvements and bug fixes. Breaking changes: * None. Deprecations: * None. Technology Preview features: * None. Enhancements: * None. Bug fixes: * gRPC-Go authorization bypass vulnerability fix: Previously, gRPC-Go was vulnerable to an authorization bypass attack. This issue occurred because the HTTP/2 :path pseudo-header was not properly validated. Remote attackers could send raw HTTP/2 frames with a malformed :path that omitted the mandatory leading slash to bypass defined security policies. With this update, gRPC-Go properly validates the :path pseudo-header and rejects malformed requests. As a result, attackers can no longer bypass security policies to gain unauthorized access to services or disclose information. For more information, see https://access.redhat.com/security/cve/cve-2026-33186. * XPath component fix: Previously, the github.com/antchfx/xpath component did not properly handle certain Boolean XPath expressions. A remote attacker could submit a crafted expression that caused an infinite loop, resulting in 100% CPU utilization and a denial-of-service condition. With this update, the XPath component correctly processes Boolean expressions that evaluate to true. The system no longer enters an infinite loop when handling these expressions. For more information, see https://access.redhat.com/security/cve/cve-2026-4645. * Go JOSE denial-of-service vulnerability fix: Previously, the Go JOSE library for handling JSON Web Encryption (JWE) objects was vulnerable to a denial-of-service (DoS) attack. This issue occurred because the application failed when decrypting a specially crafted JWE object that specified a key wrapping algorithm but contained an empty encrypted key field. With this update, Go JOSE properly validates the encrypted key field before decryption. As a result, the application no longer crashes when processing malformed JWE objects, and the service remains available to legitimate users. For more information, see https://access.redhat.com/security/cve/cve-2026-34986. * Lodash _.template function fix: Previously, the lodash _.template function validated the variable option but did not validate options.imports key names. Both options passed values to the same code execution path. An attacker with the ability to control options.imports key names or pollute Object.prototype could exploit this gap to execute arbitrary code. With this update, lodash validates options.imports key names by using the same rules applied to the variable option. The _.template function rejects invalid key names and prevents code injection through this path. For more information, see https://access.redhat.com/security/cve/cve-2026-4800. * Go crypto/x509 and crypto/tls packages fix: Previously, the Go standard library crypto/x509 and crypto/tls packages did not limit the number of intermediate certificates processed during certificate chain building. An attacker could provide an excessive number of intermediate certificates, causing the system to perform an uncontrolled amount of work and resulting in a denial-of-service condition. With this update, the packages limit the number of intermediate certificates accepted during certificate chain validation. The system rejects certificate chains that exceed this limit. For more information, see https://access.redhat.com/security/cve/cve-2026-32280. * Go Root.Chmod function fix: Previously, the Root.Chmod function in the Go standard library internal/syscall/unix package had a race condition between checking and modifying a target file. An attacker could replace the target with a symbolic link after the check but before the operation completed, causing the permission change to apply to the linked file instead. This allowed an attacker to bypass directory restrictions and change permissions on unintended files. With this update, the Root.Chmod function prevents this race condition. The function no longer follows symbolic links that replace the target during execution. For more information, see https://access.redhat.com/security/cve/cve-2026-32282. * Go crypto/x509 package fix: Previously, the Go crypto/x509 package applied excluded DNS constraints to wildcard Subject Alternative Names (SANs) in a case-sensitive manner. An attacker could bypass certificate validation by using a different case in the wildcard SAN than the excluded DNS constraint specified. This allowed the system to accept a malicious certificate that should have been rejected. With this update, the package applies DNS constraints case-insensitively when validating wildcard SANs. Certificate chain verification correctly rejects certificates that match excluded DNS constraints regardless of case. For more information, see https://access.redhat.com/security/cve/cve-2026-33810. * Go crypto/tls component fix: Previously, the Go crypto/tls component did not re-validate certificates against updated certif
