CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-18963 Account takeover in Red Hat Build of Keycloak allows an unauthenticated attacker to abuse the reset-credentials flow in the keycloak-services component to complete a password reset for any user without ever clicking the emailed verification link, letting them directly set new credentials. Because the mandatory email-ownership check can be bypassed, the flaw yields full control of arbitrary accounts (CVSS 9.1). No public exploit identified at time of analysis, and it is not listed in CISA KEV. CRITICAL 9.1 0.4% 81
PoC
CVE-2026-72526 Cross-cluster remote code execution in Red Hat Advanced Cluster Management for Kubernetes 2 (multicloud-integrations / ArgoCD pull-model integration) lets a low-privileged hub tenant who can create Application CRs redirect propagation to arbitrary managed spoke clusters. Because the Application propagation controller trusts the attacker-supplied `ocm-managed-cluster` annotation without validation, an attacker forces ArgoCD on targeted spokes to sync attacker-controlled manifests, yielding code execution or privilege escalation there. CVSS 9.9 with scope change; no public exploit identified at time of analysis and it is not listed in CISA KEV. CRITICAL 9.9 30.0% 80
No patch
CVE-2026-70398 Cross-tenant bearer-token disclosure in Red Hat Advanced Cluster Management for Kubernetes 2 (RHACM) lets an authenticated tenant abuse the GitOpsCluster controller in the multicloud-integrations component to redirect spoke-cluster credentials into a namespace they control. Because the controller acts on the tenant's behalf across trust boundaries (a confused-deputy flaw), a low-privileged user can obtain tokens that grant access to managed spoke clusters and bypass ArgoCD AppProject scoping controls. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the CVSS base score is 9.6 (Critical). CRITICAL 9.6 23.0% 71
No patch
CVE-2026-18663 Heap corruption via double-free in 389-ds-base's LDAP control parsing allows an unauthenticated remote attacker to crash the directory service with a single crafted BIND request. The flaw resides in `get_ldapmessage_controls_ext()`, which frees a parsed controls array when rejecting an unknown critical Session Tracking control but fails to clear the corresponding SLAPI_REQCONTROLS pblock slot - causing operation teardown to free the same pointer a second time. Affected deployments include Red Hat Directory Server 11 through 13 and the 389-ds-base package across all supported RHEL versions (6-10). No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; the CVSS AC:H rating reflects that reliable heap exploitation requires specific memory layout conditions rather than a trivially repeatable one-shot crash. MEDIUM 5.9 40.0% 70
No patch
CVE-2026-92574 Elevated-privilege container restoration in CRI-O 1.34 and later, including downstream Red Hat OpenShift Container Platform 4.17+, lets an authenticated Kubernetes user who can create a pod from a crafted checkpoint image bypass the destination pod's security context. The restored process keeps credentials, Linux capabilities, no_new_privs and seccomp state stored in the checkpoint instead of the destination configuration, allowing execution across the container security boundary. Exploitation requires non-default checkpoint/restore (CRIU) support to be enabled and RBAC permission to create pods from malicious checkpoints; no public exploit code is identified and no vendor-released fix is available at time of analysis, so the vendor CVSS 3.1 score of 8.8 overstates urgency given those prerequisites (our assessment raises attack complexity to High). HIGH 8.8 0.5% 65
PoC No patch
CVE-2026-66878 Secret exfiltration across Kubernetes namespace boundaries in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management for Kubernetes 2 allows an authenticated namespace administrator to read Kubernetes Secrets from arbitrary namespaces outside their own authorization domain. By setting Channel.Spec.SecretRef.Namespace to a target namespace, the attacker causes the subscription controller to autonomously copy sensitive Secret contents into a namespace the attacker controls, violating the Kubernetes namespace isolation model. No public exploit code has been identified at time of analysis, but the scope-changed CVSS vector (S:C, C:H) and the sensitivity of Kubernetes Secret payloads - which frequently contain credentials, API tokens, and TLS private keys - make this a high-priority finding in any multi-tenant RHACM deployment. HIGH 7.7 21.0% 60
No patch
CVE-2026-73122 Unauthorized cross-tenant Secret and ConfigMap access in the multicloud-operators-channel component of Red Hat Advanced Cluster Management for Kubernetes 2 allows a compromised managed-cluster agent to read all Secrets and ConfigMaps within any Channel namespace on the hub cluster. The Changed scope (S:C) in the CVSS vector confirms that exploitation pivots from a managed cluster context into the hub, exposing Git and Helm repository credentials belonging to other tenants. No public exploit has been identified at time of analysis, but the network-reachable, low-privilege vector makes this a high-priority finding in any multi-tenant RHACM deployment. HIGH 7.7 21.0% 60
No patch
CVE-2026-101258 Ghostscript can execute arbitrary shell commands with the privileges of its process when it renders a crafted PostScript or EPS document, chaining memory corruption in document parsing with a runtime bypass of the -dSAFER sandbox. The flaw affects Ghostscript as shipped in Red Hat Enterprise Linux 6, 7, 8, 9, and 10, and the assessed vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, meaning no privileges are required but a victim or automated pipeline must render the malicious file, with the malicious document first reaching the processing system. Publicly available exploit code exists, including a GitHub proof-of-concept, but the provided data does not confirm CISA KEV active exploitation, so -dSAFER should not be treated as a protective mitigation for affected versions. HIGH 7.8 0.2% 59
PoC
CVE-2026-96889 Use-after-free in librsvg during rendering of crafted SVG documents with nested XInclude directives and duplicate entity declarations allows unauthenticated local attackers to crash or potentially execute code in applications that use the library. Tracked as CVE-2026-96889 and reported by Red Hat, the flaw affects librsvg as shipped in Red Hat Enterprise Linux 6, 7, 8, 9, and 10. Exploitation requires user interaction (UI:R) because a victim must open, preview, or thumbnail a malicious SVG; the CVSS 3.1 score is 7.8. No public exploit code was identified at time of analysis, and independent assessment indicates that arbitrary code execution is unproven-only denial of service or crash is reliably reachable. HIGH 7.8 0.1% 59
PoC
CVE-2026-114406 The system CA trust store shipped in Red Hat's ca-certificates RPM packages includes eMudhra root authorities that signed intermediate CA certificates protected by weak private keys, so a man-in-the-middle attacker who can intercept traffic and who can factor or guess those keys could mint certificates for arbitrary hostnames that TLS clients using the system trust store would accept (CVSS 6.8, CWE-295). Affected platforms span Red Hat Enterprise Linux 6 through 10 plus a long list of layered products such as OpenShift Container Platform 4, Satellite 6, Quay 3, Advanced Cluster Management, and the cert-manager and logging operators. Attackers need a privileged network position and a victim client that actually initiates a TLS connection validated against the system store, so this is a trust-anchoring and impersonation problem rather than a remotely reachable code-execution flaw; there is no availability impact and no public exploit code identified at time of analysis. Because individual intermediate certificates cannot be selectively distrusted across every consumer of the system store, Red Hat is removing the parent root CAs outright, which is the crux of the remediation. MEDIUM 6.8 0.2% 54
PoC
CVE-2026-18948 Unauthenticated remote code execution affects Feast (the open-source ML feature store), where user-defined functions stored in the registry are serialized with Python's 'dill' library and deserialized without validation. In default configurations a remote attacker can store a malicious UDF and achieve unauthenticated code execution on the feature server; an authenticated attacker can bypass authorization during deserialization to run code on the registry server, enabling cross-tenant data access and lateral movement. Rated CVSS 9.9 with a scope change; no public exploit has been identified at time of analysis, and it is not listed in CISA KEV. Feast is bundled in Red Hat OpenShift AI (RHOAI), which is the reporting vendor's affected product. CRITICAL 9.9 0.7% 50
CVE-2026-84719 Missing authorization checks in the Red Hat Ansible Automation Platform 2 automation-controller allow an authenticated organization workflow-admin - a delegated, non-superuser role - to escalate into the control plane by copying a WorkflowJobTemplate and then launching jobs pinned to instance groups they hold no use_role on. The deep-copy permission sanitizer re-validates only the inventory, unified_job_template, and credentials of each cloned node, silently carrying over instance_groups, execution_environment, and labels, so the copier becomes administrator of a workflow that executes attacker-influenced automation in the control-plane execution context (CVSS 9.9, scope changed, high confidentiality, integrity, and availability impact). Exploitation is confirmed to require only a normal multi-tenant deployment plus workflow-admin rights; no public exploit code has been identified at time of analysis and there is no CISA KEV entry, and no vendor-released patch version was confirmed in the available intelligence. CRITICAL 9.9 0.4% 50
CVE-2026-14450 Authentication bypass in the Models-as-a-Service (MaaS) API component of Red Hat OpenShift AI (RHOAI) lets any pod already running in the cluster impersonate arbitrary users by forging the X-MaaS-Username and X-MaaS-Group HTTP headers, which the service trusts without independent verification. Because the MaaS API performs no first-party authentication and defers entirely to a Kuadrant AuthPolicy gateway that can be circumvented, a low-privileged workload can mint Kubernetes ServiceAccount tokens in other tenants' namespaces, revoke API keys, and exfiltrate model-access configuration - a full cross-tenant privilege escalation. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the 9.9 CVSS reflects near-total impact. CRITICAL 9.9 0.4% 50
CVE-2026-73268 Privilege escalation and arbitrary code execution in Red Hat's multicluster engine (MCE) for Kubernetes lets a low-privileged tenant holding create or update rights on ClusterCurator resources hijack the cluster-curator-controller's service account. Because the CreateJob() function unmarshals the attacker-supplied spec.install.overrideJob raw extension without validation, the injected Job runs with the controller's elevated permissions, enabling cluster-wide secret access and full compromise. Rated CVSS 9.9 by Red Hat; no public exploit identified at time of analysis and it is not listed in CISA KEV. CRITICAL 9.9 0.4% 50
No patch
CVE-2026-72508 Privilege escalation in Red Hat Advanced Cluster Management for Kubernetes 2 lets a namespace-scoped tenant abuse the multicloud-operators-subscription controller as a confused deputy: by crafting Subscription Custom Resources, a namespace-admin causes the controller's highly privileged ServiceAccount to deploy attacker-chosen cluster-scoped resources. This breaks tenant isolation and can yield cluster-wide privilege escalation and arbitrary code execution. Rated CVSS 9.9 (scope-changing), with no public exploit identified at time of analysis and no active exploitation reported (not in CISA KEV). CRITICAL 9.9 0.3% 50
