CVE-2026-10079

Description

A flaw was found in Red Hat Advanced Cluster Security for Kubernetes (RHACS). When processing Kubernetes Deployments, ACS replaces deployment identity metadata based on the openshift.io/encoded-deployment-config label. A user with permission to create Deployments can set this label to "null", causing ACS to treat the workload as having empty UID, name and labels and namespace "default". This bypasses deploy-time policy detection and enforcement visibility, prevents correct persistence in Central and breaks violation reporting and compliance correlation for the affected deployment.

Statement

Red Hat Product Security is aware of this issue affecting RHACS secured clusters. This flaw allows a user with permission to create Deployments to evade deploy-time policy visibility and enforcement for that workload and reduce the integrity of ACS security reporting. Red Hat is not aware of malicious exploitation of this issue outside of coordinated testing. Updates addressing this issue will be released according to the RHACS support lifecycle.

Mitigation

There is no complete mitigation other than installing the update once available.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
