A misconfigured NetworkPolicy in Kubernetes deployments allows attackers to perform unauthorized lateral movement between namespaces, breaking namespace isolation security boundaries. This vulnerability affects Kubernetes environments with improperly configured inter-namespace NetworkPolicies, specifically those with 'inter-ns' prefixed policies in monitoring namespaces. An attacker who compromises any component can pivot to access resources in other namespaces, potentially accessing sensitive data or systems they shouldn't have access to.

OneUptime versions prior to 10.0.24 contain a sensitive information exposure vulnerability where the password reset flow logs complete password reset URLs containing plaintext reset tokens at the INFO log level, which is enabled by default in production environments. Any actor with access to application logs-including log aggregation systems, Docker logs, or Kubernetes pod logs-can extract these tokens and perform account takeover on any user. The vulnerability is fixed in version 10.0.24.

Silent event loss in Inspektor Gadget prior to 0.50.1 allows local attackers to cause denial of service by filling the 256KB ring-buffer, which triggers undetected data drops without alerting users or administrators. When the buffer becomes full, gadgets silently discard events and fail to report the loss count, potentially hiding critical system events from Kubernetes cluster and Linux host monitoring. A local attacker with limited privileges can exploit this to obscure malicious activity or system anomalies by saturating the instrumentation buffer.

Medium severity vulnerability in HashiCorp Consul. HashiCorp Consul and Consul Enterprise 1.18.20 up to 1.21.10 and 1.22.4 are vulnerable to arbitrary file read when configured with Kubernetes authentication. This vulnerability, CVE-2026-2808, is fixed in Consul 1.18.21, 1.21.11 and 1.22.5.

Kubernetes flagd feature flag daemon versions before 0.14.2 are vulnerable to denial of service through unbounded memory allocation on publicly accessible evaluation endpoints. An unauthenticated attacker can send HTTP requests with arbitrarily large payloads to exhaust memory and crash the service. This affects deployments without external authentication controls, allowing trivial process termination in containerized environments.

Argo Workflows versions 2.9.0 through 4.0.1 (and 3.x before 3.7.11) allow authenticated users to bypass WorkflowTemplate security policies by injecting a podSpecPatch field in workflow submissions, circumventing even strict template referencing controls. An attacker with workflow submission privileges can exploit this to modify pod specifications without security validation, potentially gaining unauthorized access or executing arbitrary code. This vulnerability affects organizations using Kubernetes with Argo Workflows and requires upgrading to versions 4.0.2, 3.7.11 or later to remediate.

Auth bypass in Argo Workflows before 4.0.2/3.7.11.

Kubewarden's deprecated host-callback APIs in AdmissionPolicy can be exploited by authenticated users with policy creation permissions to gain unauthorized read access to cluster-level resources including Ingresses, Namespaces, and Services. An attacker with privileged AdmissionPolicy creation permissions—not a default privilege—could craft malicious policies to bypass intended access controls and enumerate sensitive cluster infrastructure, though this vulnerability is limited to read-only access without write capability or access to Secrets and ConfigMaps. The vulnerability affects Kubernetes deployments using Kubewarden and currently has no available patch.

Arbitrary code execution in ingress-nginx controllers via malicious rewrite-target annotations allows authenticated attackers to execute commands and exfiltrate cluster secrets.

Strimzi Kafka Operator versions 0.49.0-0.50.0 incorrectly trusts all intermediate CAs in a multistage certificate chain for mTLS authentication, allowing any user with a certificate signed by any CA in the chain to authenticate to Kafka listeners. This authentication bypass affects only deployments using custom Cluster or Clients CA with multi-level CA chains. No patch is currently available.

Strimzi versions 0.47.0 through 0.50.0 improperly trust all certificates in a CA chain rather than only the intended signing authority, allowing Kafka Connect and MirrorMaker 2 operands to accept connections from brokers with certificates signed by intermediate CAs. An attacker could leverage this improper certificate validation to establish unauthorized connections to Kafka clusters using alternate CA-signed certificates from the trusted chain. This vulnerability requires high privileges to configure the CA chain and has no available patch at this time.

Authorization bypass in Kargo Kubernetes promotion tool from 1.7.0 before 1.7.8/1.8.11/1.9.3. Batch resource creation bypasses authorization checks. Patch available.

Kargo versions 1.9.0 through 1.9.2 fail to enforce the custom "promote" authorization verb in three REST API endpoints, allowing authenticated users with standard Kubernetes RBAC permissions to trigger promotions without the intended fine-grained access controls. An attacker with patch permissions on freight status or create permissions on promotions can bypass promotion pipeline restrictions and advance software artifacts unauthorized. A patch is available to restore the missing authorization checks.

Arbitrary code execution in Yoke's Air Traffic Controller component allows authenticated users with CustomResource create/update permissions to execute malicious WebAssembly modules by injecting crafted URLs into the overrides.yoke.cd/flight annotation, potentially enabling cluster-admin privilege escalation. The vulnerability affects Yoke 0.19.0 and earlier, with no patch currently available and an 8.8 CVSS severity rating.

Unauthenticated webhook endpoints in Yoke's Air Traffic Controller component allow any pod within a Kubernetes cluster to submit AdmissionReview requests and execute WASM modules in the controller's context without authorization. This affects Yoke versions 0.19.0 and earlier, enabling attackers with cluster access to bypass API Server authentication and potentially compromise the infrastructure-as-code deployment pipeline. No patch is currently available.

Cluster administrators running affected Flux Operator versions should upgrade to 0.40.0 or later.

Stored XSS in Argo Workflows artifact directory listing (versions prior to 3.6.17 and 3.7.8) allows workflow authors to inject malicious JavaScript that executes in other users' browsers under the Argo Server origin. An attacker can leverage the victim's session to perform API actions and access resources with their privileges. Public exploit code exists for this vulnerability; patched versions are available.

External Secrets Operator versions 0.20.2 through 1.1.x contain an authorization bypass in the getSecretKey template function that allows authenticated users to retrieve secrets across namespace boundaries, circumventing intended access controls. An attacker with local Kubernetes access could exploit this to exfiltrate sensitive data managed by the operator outside their authorized namespace. The vulnerability has been patched in version 1.2.0 where the function was completely removed.

Skipper versions before 0.23.0 allow authenticated users with Ingress resource creation privileges to execute arbitrary Lua scripts that read sensitive filesystem data and secrets accessible to the Skipper process. The vulnerability stems from the default -lua-sources=inline configuration enabling untrusted users to create inline Lua filters. Public exploit code exists for this high-severity vulnerability affecting Kubernetes environments running vulnerable Skipper versions.

This affects Headlamp versions prior to 0.31.1, and while no active KEV or confirmed public POC is mentioned in available data, the vulnerability has a moderate-to-high CVSS score of 7.7 with user interaction required, making it a realistic threat in CI/CD and development environments.

Helm is a package manager for Charts for Kubernetes. Prior to 3.18.4, a specially crafted Chart.yaml file along with a specially linked Chart.lock file can lead to local code execution when dependencies are updated. Fields in a Chart.yaml file, that are carried over to a Chart.lock file when dependencies are updated and this file is written, can be crafted in a way that can cause execution if that same content were in a file that is executed (e.g., a bash.rc file or shell script). If the Chart.lock file is symlinked to one of these files updating dependencies will write the lock file content to the symlinked file. This can lead to unwanted execution. Helm warns of the symlinked file but did not stop execution due to symlinking. This issue has been resolved in Helm v3.18.4.

MCP Server Kubernetes is an MCP Server that can connect to a Kubernetes cluster and manage it. A command injection vulnerability exists in the mcp-server-kubernetes MCP Server.
