Title
Clusterclaims-controller: clusterclaims-controller: managedcluster deletion keyed solely on clusterclaim.spec.namespace with no ownership check
Summary
A flaw was found in the clusterclaims-controller component of multicluster engine (MCE). A tenant with standard permissions to create and delete ClusterClaim resources can exploit this by manipulating the `spec.namespace` field. This allows the tenant to specify and delete any ManagedCluster, including the hub's local-cluster or other tenants' clusters, due to a missing ownership check. This vulnerability can lead to a denial of service by enabling unauthorized deletion of ManagedClusters.

Title
Multicloud-operators-subscription: multicloud-operators-subscription: cross-namespace secret exfiltration via helmrelease.repo.secretref.namespace
Summary
A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). A tenant with HelmRelease create permissions can exploit this vulnerability by manipulating the `secretRef.Namespace` field. This allows the `GetSecret()` function in the HelmRelease controller to fetch sensitive credentials from any namespace, which are then sent to an attacker-controlled Helm repository. This can lead to the exfiltration of credentials from arbitrary namespace Secrets, resulting in information disclosure.

Title
Multicloud-operators-subscription: multicloud-operators-subscription: helmrelease chart applied with controller sa without gvk or namespace restriction
Summary
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a tenant, who has the ability to create HelmRelease custom resources (CRs), to bypass existing security controls. The system's HelmRelease controller processes Helm chart templates using its own elevated ServiceAccount privileges without proper validation. This enables the tenant to deploy arbitrary resources across the entire cluster, leading to a significant security compromise.

Title
Lighthouse: lighthouse: arbitrary local-namespace injection via attacker-controlled labelsourcenamespace
Summary
A flaw was found in Lighthouse. A remote attacker, by compromising a spoke cluster, can exploit a vulnerability where the destination namespace for resource injection is derived from an attacker-controlled label or annotation on the broker object. This allows the attacker to inject unauthorized EndpointSlices and ServiceImports into any namespace on peer clusters, including critical system namespaces like kube-system and openshift-*. This could lead to privilege escalation or other forms of system compromise within the cluster.

Title
Lighthouse: lighthouse: cross-cluster dns spoofing via unvalidated endpointslice and serviceimport ips
Summary
A flaw was found in the lighthouse component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability stems from insufficient validation of advertised IP addresses within EndpointSlice objects. A compromised spoke cluster can exploit this by creating EndpointSlices with attacker-controlled IP addresses, causing other clusters' lighthouse DNS to redirect legitimate service traffic to malicious endpoints. This enables a remote attacker to conduct transparent Man-in-the-Middle (MITM) attacks on cross-cluster service communications, potentially leading to unauthorized information disclosure and data manipulation.

Title
Submariner: submariner: unvalidated endpoint.spec.subnets propagated into wireguard allowedips / ipsec enables traffic hijack
Summary
A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.

Kata-containers: insufficient validation of createcontainer mount and storage rules in genpolicy
Summary
A flaw was found in Kata Containers. In configurations utilizing genpolicy for Confidential Containers guest protection, a malicious host operator can exploit insufficient validation of CreateContainer mount and storage rules. This allows them to mount arbitrary container-rootfs paths over sensitive host locations or provision arbitrary content, potentially exposing confidential information or enabling the acceptance of attacker-controlled input.

A flaw was found in WildFly Elytron. Password hashing and verification normalize input with Unicode NFKC, which can collapse fullwidth characters to ASCII equivalents. A remote attacker can more easily guess affected passwords by using an ASCII-only dictionary against accounts whose passwords were intended to include those non-ASCII characters, leading to unauthorized access.

Title
Ipa: freeipa: null pointer dereference in `ipa-enrollment` extended operation (`join_oid`) via missing request value
Summary
A flaw was found in the `ipa-enrollment` SLAPI plugin. A remote authenticated client can exploit a null pointer dereference vulnerability by sending a malformed Lightweight Directory Access Protocol (LDAP) extended operation. By omitting the request value for the `JOIN_OID` in the `ipa-enrollment` extended operation, an attacker can trigger a server crash, potentially causing a denial of service.

Ipa: freeipa: unauthenticated dos in `/ipa/i18n_messages` via unbounded request body read
Summary
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.

Title
Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read
Summary
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.

Title
Ipa: freeipa: authenticated dos in `otptoken-add` via unbounded otp key decoding/re-encoding
Summary
A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service.

Title
Ipa: privilege escalation via krbcanonicalname manipulation due to realm-unaware uniqueness enforcement in freeipa ldap datastore
Summary
A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one. This can lead to unauthorized acquisition of Kerberos service tickets for sensitive services, potentially resulting in full domain compromise.

Title
Freeipa: idm: ipa: freeipa: obtaining tgs with impersonating cname through trust relationships
Summary
A flaw was found in FreeIPA. When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket Granting Service (TGS) due to FreeIPA services not verifying Privilege Attribute Certificate (PAC) certificates. This vulnerability could allow an authenticated Active Directory user to escalate their privileges within the FreeIPA domain.

Title
Libvirt: integer overflow in nodegetfreepages rpc handler leading to heap buffer overflow
Summary
A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denial of service or local privilege escalation.

Title
Libsoup: libsoup: integer truncation in sort_ranges() comparator causes silent omission of http range responses
Summary
A flaw was found in libsoup's SoupServer HTTP Range header processing. The sort_ranges() comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INT_MAX. This causes silent omission of requested byte ranges from HTTP 206 Partial Content responses on resources larger than approximately 2 GB.

Title
Search-indexer: search-indexer: update/delete operations not scoped to caller's cluster (cross-tenant data tampering)
Summary
A flaw was found in search-indexer. This vulnerability allows a registered and authenticated managed cluster to tamper with or delete another cluster's indexed search data. This is possible because the delta-sync write paths in search-indexer do not properly restrict UPDATE/DELETE operations to data owned by the calling cluster. An attacker could exploit this by crafting specific user identifiers (UIDs) with a different cluster's prefix.

Title
Acm-operator-bundle: acm-operator-bundle: bundle build execs unpinned stolostron/release@master with full build credentials
Summary
A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.

Title
Mce-operator-bundle: mce-operator-bundle: bundle-generation business logic fetched from mutable stolostron/release@master
Summary
A flaw was found in mce-operator-bundle. The build process fetches and executes scripts from a remote repository without performing integrity checks, such as commit pinning or signature verification. This allows a malicious actor with write access to the remote repository to inject and execute arbitrary code during the build. The consequence is a compromised build process, potentially leading to the distribution of malicious software.

Title
Search-v2-operator: search-v2-operator: operator clusterrole is cluster-admin equivalent via impersonate, rbac write, csr approve, and manifestwork
Summary
A flaw was found in search-v2-operator. The operator's ClusterRole has permissions equivalent to a cluster administrator, allowing it to impersonate other entities, write Role-Based Access Control (RBAC) configurations, approve Certificate Signing Requests (CSRs), and manage ManifestWork. This grants excessive privileges beyond what is necessary for the operator's intended function, potentially leading to privilege escalation within the cluster.

Title
Cluster-proxy-addon: cluster-proxy-addon: unauthenticated ssrf to arbitrary managed-cluster services via public route
Summary
A flaw was found in the `cluster-proxy-addon` component of Multicluster Engine for Kubernetes. This vulnerability allows an unauthenticated attacker, who can access the user-facing route, to bypass authentication and authorization checks. By manipulating URL path segments, the attacker can proxy requests to arbitrary services across any managed cluster. This enables unauthorized access to internal services that would otherwise be protected, potentially leading to information disclosure or further compromise of the cluster environment.

Volsync-addon-controller: volsync-addon-controller: annotation values rendered into yaml via text/template without escaping allows yaml injection into subscription
Summary
A flaw was found in volsync-addon-controller. This vulnerability allows an attacker to inject malicious YAML (Yet Another Markup Language) code into the OpenShift Lifecycle Manager (OLM) Subscription resource. This is due to improper escaping of annotation values when they are rendered into YAML. Successful exploitation could lead to unauthorized modification or control over OLM Subscription configurations, potentially impacting software management within the cluster. This issue primarily affects systems where the 'volsync-addon-deploy-type: olm' annotation is explicitly enabled.

Title
Acm-search-v2-rhel9: search-v2-operator: search cr imageoverride/arguments/envvar flow unsanitized into pods running impersonating sa
Summary
A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.

Title
Vim: vimscript injection via unescaped filename in netrw s:netrwmarkfile() filter() expression allows arbitrary code execution
Summary
A flaw was found in Vim's netrw plugin. A crafted filename containing quote characters and expression fragments can break out of the quoted context during mark/unmark operations, allowing arbitrary Vimscript execution. This can be leveraged to run shell commands with the privileges of the user running Vim.

Title
Modcluster-core: mod_cluster advertise listener: unauthenticated dos via crafted multicast datagram
Summary
A flaw was found in mod_cluster's AdvertiseListenerImpl (org.jboss.modcluster core module). A single crafted UDP multicast datagram with a valid HTTP status line and a "Server:" header but without the "Date:", "Digest:", and "Sequence:" headers triggers a NullPointerException in verifyDigest() that is not caught by the worker thread's exception handler. This causes the advertise listener thread to terminate permanently. The failure is silent (isListening() continues to return true) and persists until the node is restarted. The crash occurs before the AdvertiseSecurityKey comparison, so deployments with a configured security key are still affected.

Title
Swtpm: swtpm: out-of-bounds read in swtpm_nvram_checkheader due to sizeof(pointer) vs sizeof(struct) mismatch
Summary
An out-of-bounds read vulnerability was found in swtpm's SWTPM_NVRAM_CheckHeader() function. The entry guard checks the buffer length against sizeof(bh), where bh is a pointer, instead of sizeof(*bh), the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overread on 64-bit systems (6 bytes on 32-bit) when accessing the totlen field. This may cause daemon termination on some platforms and leaks heap data to the log.

Title
Keycloak-services: keycloak-services: predictable account-linking hash enables account takeover via malicious oidc client
Summary
A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim's account to an attacker's external identity. This results in a full account takeover, allowing the attacker to log in as the victim.

The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim\u0027s account to an attacker\u0027s external identity. This results in a full account takeover, allowing the attacker to log in as the victim."

CVE-2026-66780 (GCVE-0-2026-66780)
Vulnerability from nvd – Published: 2026-08-18 17:32 – Updated: 2026-08-18 18:45

Title
Submariner-operator: submariner-operator: flat broker trust model grants every spoke full crud on all endpoints, secrets, and endpointslices in broker namespace
Summary
A flaw was found in the submariner-operator component. The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.
