CVE-2026-81521: Improper Control of Resource Identifiers

The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name...

Name of the Vulnerable Software and Affected Versions openssl encrypt versions prior to 1.4.9 Description The software fails to prevent namespace collisions between own identities and contacts within the IdentityStore. This allows attackers to create shadowed contact entries that remain invisible...

PT-2026-82738

Name of the Vulnerable Software and Affected Versions MongoDB C Driver affected versions not specified Description A weakness exists where the driver fails to sanitize special elements in caller-supplied database and collection name components during the composition of the target namespace for an...

Name of the Vulnerable Software and Affected Versions MongoDB C++ Driver affected versions not specified Description A weakness in the handling of caller-supplied namespace identifiers allows the embedding of special characters. If an application constructs a namespace identifier using untrusted...

CVE-2026-81525: Improper Neutralization of Special Elements in Data Query Logic

The MongoDB client library for PHP does not sufficiently sanitize special elements in application-supplied namespace identifiers before using them to construct the target namespace for database operations. An application that incorporates untrusted text into these identifiers may have operations...

CVE-2026-81524: Improper Control of Resource Identifiers

A weakness in the MongoDB C Driver allows special elements in caller-supplied database and collection name components to pass without sanitization when the driver composes the target namespace for an operation. An application that incorporates untrusted input into these name components can have...

CVE-2026-81522: Improper Encoding or Escaping of Output

A weakness in the MongoDB C++ Driver's handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application that builds a namespace identifier from untrusted input without validating it may therefore have its operation directed at a different...

CVE-2026-81706: Insufficient Verification of Data Authenticity

opensslencrypt before 1.4.9 fails to prevent namespace collisions between own identities and contacts in IdentityStore, allowing attackers to create shadowed contact entries invisible until the corresponding own identity is deleted. When the own identity is deleted, the shadowed contact becomes...

UBUNTU-CVE-2026-79619

On Linux, several OpenZFS ioctl authorization checks accept a capability held only within a user-created, unprivileged namespace as equivalent to real host privilege, allowing an unprivileged local user to perform operations that should require root. Affected operations include pool-administrativ...

CVE-2026-71327

A flaw was found in Traefik, an open-source HTTP reverse proxy and load balancer. Its Kubernetes Gateway API provider incorrectly generates unique identifiers for routes and services. This vulnerability allows an attacker to create conflicting routes, which can then overwrite the backend services...

CVE-2026-71325

A flaw was found in Traefik. This flaw allows a tenant, even when restricted by Role-Based Access Control RBAC to a single namespace, to bypass namespace isolation. By binding their own router to a TraefikService in another namespace, an attacker can expose or reroute that namespace's backend...

CVE-2026-54523

Kyverno is a policy engine designed for cloud native platform engineering teams. From 1.18.0 until 1.18.2, the NamespacedMutatingPolicy CEL compiler exposes the generator library to matchConditions, allowing a namespace-scoped policy to invoke generator.applynamespace, resources with an arbitrary...

Kyverno's NamespacedGeneratingPolicy generator.apply() namespace argument unvalidated -- background controller creates RoleBindings in any namespace including kube-system

Summary In Kyverno v1.18.1, a tenant who can create a NamespacedMutatingPolicy in their own namespace can instruct the admission controller to generate resources in any namespace by passing an arbitrary namespace string to the CEL generator.applynamespace, resources function. Details...

CVE-2026-54523

Kyverno (a policy engine for cloud native platforms) versions 1.18.0 through 1.18.1 are affected by a namespace-scope validation bypass in the NamespacedMutatingPolicy CEL compiler. The function GenerateResources in pkg/cel/libs/context.go does not reject cross-namespace targets, and the validato...
