CVE-2026-10079 — Stackrox: stackrox: deploy-time policy enforcement and visibility bypass via label injection
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat Advanced Cluster Security 4).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (integrity), errors and authentication anomalies.
