CWE-653

Improper Isolation or Compartmentalization

ClassDraft

Description

The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.

When a weakness occurs in functionality that is accessible by lower-privileged users, then without strong boundaries, an attack might extend the scope of the damage to higher-privileged users.

CVE-2025-1974Cri0.749.80.91Mar 25, 2025A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
CVE-2026-0542Cri0.60—0.00Feb 25, 2026ServiceNow has addressed a remote code execution vulnerability that was identified in the ServiceNow AI platform. This vulnerability could enable an unauthenticated user, in certain circumstances, to execute code within the ServiceNow Sandbox.    ServiceNow addressed this vulnerability by deploying a security update to hosted instances. Relevant security updates also have been provided to ServiceNow self-hosted customers and partners. Further, the vulnerability is addressed in the listed patches and hot fixes. While we are not currently aware of exploitation against customer instances, we recommend customers promptly apply appropriate updates or upgrade if they have not already done so.
CVE-2025-4083Cri0.599.10.00Apr 29, 2025A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10.
CVE-2025-12805Hig0.538.10.00Mar 26, 2026A flaw was found in Red Hat OpenShift AI (RHOAI) llama-stack-operator. This vulnerability allows unauthorized access to Llama Stack services deployed in other namespaces via direct network requests, because no NetworkPolicy restricts access to the llama-stack service endpoint. As a result, a user in one namespace can access another user’s Llama Stack instance and potentially view or manipulate sensitive data.
CVE-2025-20109Hig0.517.80.00Aug 12, 2025Improper Isolation or Compartmentalization in the stream cache mechanism for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.
CVE-2025-53710Hig0.497.50.00Dec 18, 2025Due to a product misconfiguration in certain deployment types, it was possible from different pods in the same namespace to communicate with each other. This issue resulted in bypass of access control due to the presence of a vulnerable endpoint in Foundry Container Service that executed user-controlled commands locally.
CVE-2026-5599Hig0.47—0.00Apr 5, 2026A user with API access and "manage users" permission in any venueless world is able to trigger deletion of user accounts in other worlds.
CVE-2025-41688Hig0.477.20.00Jul 31, 2025A high privileged remote attacker can execute arbitrary OS commands using an undocumented method allowing to escape the implemented LUA sandbox.
CVE-2026-34775Med0.446.80.00Apr 4, 2026Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0, the nodeIntegrationInWorker webPreference was not correctly scoped in all configurations. In certain process-sharing scenarios, workers spawned in frames configured with nodeIntegrationInWorker: false could still receive Node.js integration. Apps are only affected if they enable nodeIntegrationInWorker. Apps that do not use nodeIntegrationInWorker are not affected. This issue has been patched in versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0.
CVE-2026-4282Hig0.417.40.00Apr 2, 2026A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an unauthenticated attacker to forge authorization codes. Successful exploitation can lead to the creation of admin-capable access tokens, resulting in privilege escalation.
CVE-2026-25905Med0.385.80.00Feb 9, 2026The Python code being run by 'runPython' or 'runPythonAsync' is not isolated from the rest of the JS code, allowing any Python code to use the Pyodide APIs to modify the JS environment. This may result in an attacker hijacking the MCP server - for malicious purposes including MCP tool shadowing. Note - the "mcp-run-python" project is archived and unlikely to receive a fix.
CVE-2025-12695Med0.385.90.00Nov 4, 2025The overly permissive sandbox configuration in DSPy allows attackers to steal sensitive files in cases when users build an AI agent which consumes user input and uses the “PythonInterpreter” class.
CVE-2026-41174Med0.356.40.00Apr 30, 2026Traefik is an HTTP reverse proxy and load balancer. Prior to versions 2.11.43, 3.6.14, and 3.7.0-rc.2, there is a potential vulnerability in Traefik's Kubernetes CRD provider cross-namespace isolation enforcement. When providers.kubernetesCRD.allowCrossNamespace=false, Traefik correctly rejects direct cross-namespace middleware references from IngressRoute objects, but fails to apply the same restriction to middleware references nested inside a Chain middleware's spec.chain.middlewares[]. An actor with permission to create or update Traefik CRDs in their own namespace can exploit this to cause Traefik to resolve and apply middleware objects from another namespace, bypassing the documented isolation boundary. This issue has been patched in versions 2.11.43, 3.6.14, and 3.7.0-rc.2.
CVE-2025-29781Med0.356.50.00Mar 17, 2025The Bare Metal Operator (BMO) implements a Kubernetes API for managing bare metal hosts in Metal3. Baremetal Operator enables users to load Secret from arbitrary namespaces upon deployment of the namespace scoped Custom Resource `BMCEventSubscription`. Prior to versions 0.8.1 and 0.9.1, an adversary Kubernetes account with only namespace level roles (e.g. a tenant controlling a namespace) may create a `BMCEventSubscription` in his authorized namespace and then load Secrets from his unauthorized namespaces to his authorized namespace via the Baremetal Operator, causing Secret Leakage. The patch makes BMO refuse to read Secrets from other namespace than where the corresponding BMH resource is. The patch does not change the `BMCEventSubscription` API in BMO, but stricter validation will fail the request at admission time. It will also prevent the controller reading such Secrets, in case the BMCES CR has already been deployed. The issue exists for all versions of BMO, and is patched in BMO releases v0.9.1 and v0.8.1. Prior upgrading to patched BMO version, duplicate any existing Secret pointed to by `BMCEventSubscription`'s `httpHeadersRef` to the same namespace where the corresponding BMH exists. After upgrade, remove the old Secrets. As a workaround, the operator can configure BMO RBAC to be namespace scoped, instead of cluster scoped, to prevent BMO from accessing Secrets from other namespaces, and/or use `WATCH_NAMESPACE` configuration option to limit BMO to single namespace.
CVE-2025-26393Med0.355.40.00Mar 17, 2025SolarWinds Service Desk is affected by a broken access control vulnerability. The issue allows authenticated users to escalate privileges, leading to unauthorized data manipulation.
CVE-2024-5801Med0.34—0.00Aug 12, 2024Enabled IP Forwarding feature in B&R Automation Runtime versions before 6.0.2 may allow remote attack-ers to compromise network security by routing IP-based packets through the host, potentially by-passing firewall, router, or NAC filtering.
CVE-2024-8118Med0.33—0.00Sep 26, 2024In Grafana, the wrong permission is applied to the alert rule write API endpoint, allowing users with permission to write external alert instances to also write alert rules.
CVE-2026-5600Med0.284.30.00Apr 8, 2026A new API endpoint introduced in pretix 2025 that is supposed to return all check-in events of a specific event in fact returns all check-in events belonging to the respective organizer. This allows an API consumer to access information for all other events under the same organizer, even those they should not have access to. These records contain information on the time and result of every ticket scan as well as the ID of the matched ticket. Example: { "id": 123, "successful": true, "error_reason": null, "error_explanation": null, "position": 321, "datetime": "2020-08-23T09:00:00+02:00", "list": 456, "created": "2020-08-23T09:00:00+02:00", "auto_checked_in": false, "gate": null, "device": 1, "device_id": 1, "type": "entry" } An unauthorized user usually has no way to match these IDs (position) back to individual people.
CVE-2026-40968Med0.274.20.00Apr 28, 2026When an authenticated user is denied access to a gRPC method, their authenticated identity remains bound to the gRPC worker thread and can be inherited by a subsequent unauthenticated request on the same thread. This may allow the subsequent user to gain escalated permissions. Affected versions: Spring gRPC: 1.0.0 - 1.0.2 (fixed in 1.0.3). Older, unsupported versions are also affected.
CVE-2026-4325Med0.275.30.00Apr 2, 2026A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an attacker to delete arbitrary single-use entries, which can enable the replay of consumed action tokens, such as password reset links. This could lead to unauthorized access or account compromise.
