Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to 0.13.8, CapsuleConfiguration.Spec.NodeMetadata.ForbiddenLabels.Regex and CapsuleConfiguration.Spec.NodeMetadata.ForbiddenAnnotations.Regex were not validated by the configuration admission webhook, allowing a Cluster Admin to store a…

The Backup and Staging by WP Time Capsule plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.22.26 via the download_recent_decrypted_file_wptc. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract download the…

WordPress Time Capsule Plugin 1.21.16 contains an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by sending a crafted POST request with the IWP_JSON_PREFIX header. Attackers can exploit this flaw to obtain valid administrator session cookies and access the…

Capsule is a multi-tenancy and policy-based framework for Kubernetes. To defend against namespace hijacking achieved through update/patch operations on namespaces, Capsule uses a webhook to validate update requests targeting namespaces. However, in Kubernetes, the namespace/finalize and namespace/status subresource…

Capsule is a multi-tenancy and policy-based framework for Kubernetes. The Capsule Controller runs with cluster-admin privileges. Although the TenantResource RawItems processing logic forcibly sets the namespace, this is ineffective for cluster-scoped resources. Prior to version 0.13.0, tenant administrators can…

Authentication Bypass Using an Alternate Path or Channel vulnerability in revmakx Backup and Staging by WP Time Capsule wp-time-capsule allows Password Recovery Exploitation.This issue affects Backup and Staging by WP Time Capsule: from n/a through <= 1.22.25.

n authorization flaw in Foreman's GraphQL API allows low-privileged users to access metadata beyond their assigned permissions. Unlike the REST API, which correctly enforces access controls, the GraphQL endpoint does not apply proper filtering, leading to an authorization bypass.

Capsule is a multi-tenancy and policy-based framework for Kubernetes. A namespace label injection vulnerability in Capsule v0.10.3 and earlier allows authenticated tenant users to inject arbitrary labels into system namespaces (kube-system, default, capsule-system), bypassing multi-tenant isolation and potentially…

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in revmakx Backup and Staging by WP Time Capsule wp-time-capsule allows Reflected XSS.This issue affects Backup and Staging by WP Time Capsule: from n/a through <= 1.22.23.

The Backup and Staging by WP Time Capsule plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the the UploadHandler.php file and no direct file access prevention in all versions up to, and including, 1.22.21. This makes it possible for unauthenticated attackers to upload…

Capsule is a multi-tenancy and policy-based framework for Kubernetes. In Capsule v0.7.0 and earlier, the tenant-owner can patch any arbitrary namespace that has not been taken over by a tenant (i.e., namespaces without the ownerReference field), thereby gaining control of that namespace. Version 0.7.1 contains a patch.

Improper Privilege Management vulnerability in Revmakx Backup and Staging by WP Time Capsule allows Privilege Escalation, Authentication Bypass.This issue affects Backup and Staging by WP Time Capsule: from n/a through 1.22.20.

capsule-proxy is a reverse proxy for the capsule operator project. Affected versions are subject to a privilege escalation vulnerability which is based on a missing check if the user is authenticated based on the `TokenReview` result. All the clusters running with the `anonymous-auth` Kubernetes API Server setting…

capsule-proxy is a reverse proxy for Capsule kubernetes multi-tenancy framework. A bug in the RoleBinding reflector used by `capsule-proxy` gives ServiceAccount tenant owners the right to list Namespaces of other tenants backed by the same owner kind and name.
