Openshift/installer: openshift installer: unconditional csr approval during agent-based installation (abi) bootstrap
During ABI bootstrap, the bootstrap node's approve-csr.service approves and signs every CSR without identity validation. An attacker on the install network can retrieve the unauthenticated Ignition file (ports 22623/22624), extract a limited kubeconfig, submi…

Podman: goroutine/file-descriptor leak in storage/pkg/archive.applylayer and applyuncompressedlayer on malformed layers
storage/pkg/archive.ApplyLayer and ApplyUncompressedLayer may, when processing corrupt or malicious inputs, leak a file descriptor; unbounded repeated calls can exhaust the process’ file descriptor limit

Maestro: maestro: grpc broker has no auth interceptor and client mtls is optional
A flaw was found in the maestro gRPC broker. This vulnerability allows a remote attacker, with a valid client certificate, to bypass authentication. This bypass enables the attacker to subscribe to other consumers' event streams, leading to unauthorized infor…

Maestro: maestro: rest api write endpoints registered without authentication middleware
A flaw was found in Maestro. Its REST API write endpoints were registered without proper authentication middleware. This allows a remote attacker to perform unauthorized write operations, such as creating, modifying, or deleting consumers and resource bundles…

Maestro: sql identifier injection via properties.* search filter and orderby field
A flaw was found in maestro. A remote attacker could exploit a SQL injection vulnerability in the `orderBy` query parameter of its REST API list endpoints. This flaw, which does not require authentication, allows for read-only blind extraction of data from th…

Hypershift: hypershift: unsanitized kubeconfig passthrough from tenant namespace to control plane
A flaw was found in the HyperShift operator. The operator copies user-provided Kubernetes configuration (kubeconfig) secrets directly into the privileged control plane namespace without proper validation or sanitization. An authenticated user with cluster and…

Managed-serviceaccount: managed-serviceaccount: hub addon-manager clusterrole grants cluster-wide secret read/write and csr approval
A flaw was found in managed-serviceaccount. A compromised addon-manager pod, due to its ClusterRole granting excessive permissions, can read any secret across all namespaces. Additionally, it can approve arbitrary Certificate Signing Requests (CSRs), which co…

Hypershift: konnectivity proxy-server accepts agent connections without validating client certificates
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 atta…

Networkmanager: networkmanager: local privilege escalation via malformed mud urls in dhclient backend
A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by tri…

Assisted-service: assisted-service: infraenv status leaks referenced pull-secret contents to namespace view users
ACM/MCE assisted-service writes raw referenced pull-secret contents into `InfraEnv.status.conditions[].message` when pull-secret validation fails. A namespace principal with the stock `view` ClusterRole cannot directly read Secrets, but can read `InfraEnv` ob…

Mce: privilege escalation via excessive /etc/passwd permissions
A container privilege escalation flaw was found in certain Multicluster Engine for Kubernetes images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execut…

Rhacm: open cluster management (ocm): cross-cluster privilege escalation via improper kubernetes client certificate renewal validation
A flaw was found in Open Cluster Management (OCM), the technology underlying Red Hat Advanced Cluster Management (ACM). Improper validation of Kubernetes client certificate renewal allows a managed cluster administrator to forge a client certificate that can …

Operator-sdk: privilege escalation due to incorrect permissions of /etc/passwd
Early versions of Operator-SDK provided an insecure method to allow operator containers to run in environments that used a random UID. Operator-SDK before 0.15.2 provided a script, user_setup, which modifies the permissions of the /etc/passwd file to 664 duri…

Hive: exposure of vcenter credentials via clusterprovision in hive / mce / acm
A flaw was found in Hive, a component of Multicluster Engine (MCE) and Advanced Cluster Management (ACM). This vulnerability causes VCenter credentials to be exposed in the ClusterProvision object after provisioning a VSphere cluster. Users with read access t…

Cert-manager: potential dos when parsing specially crafted pem inputs
A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of…

Containers/image: digest type does not guarantee valid type
A flaw was found in the github.com/containers/image library. This flaw allows attackers to trigger unexpected authenticated registry accesses on behalf of a victim user, causing resource exhaustion, local path traversal, and other attacks.
