CVE-2024-13484
📋 TL;DR
This vulnerability in openshift-gitops-operator allows namespaces deploying ArgoCD CR instances to create rogue PrometheusRules that affect the entire cluster monitoring stack. The openshift.io/cluster-monitoring label is incorrectly applied, enabling unauthorized monitoring rule deployment. This affects OpenShift environments using the openshift-gitops-operator.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
An attacker could deploy malicious PrometheusRules that disrupt or manipulate the entire cluster monitoring stack, potentially hiding malicious activity, causing false alerts, or disrupting monitoring services across all namespaces.
Likely Case
Accidental or misconfigured deployment of PrometheusRules that interfere with legitimate monitoring, causing alert fatigue, monitoring gaps, or performance issues in the monitoring infrastructure.
If Mitigated
With proper namespace isolation and RBAC controls, the impact is limited to monitoring rule conflicts within authorized namespaces only.
🎯 Exploit Status
Requires namespace-level access to deploy ArgoCD CR instances. The vulnerability is in the automatic labeling mechanism rather than a direct code execution flaw.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in openshift-gitops-operator versions referenced in RHSA-2025:7753, RHSA-2025:8274, and RHSA-2025:9506
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2024-13484
Restart Required: No
Instructions:
1. Update openshift-gitops-operator to the patched version using OpenShift's operator lifecycle management. 2. Apply the relevant RHSA updates for your OpenShift version. 3. Verify the fix by checking that the openshift.io/cluster-monitoring label is no longer automatically applied to namespaces with ArgoCD CR instances.
🔧 Temporary Workarounds
Remove cluster-monitoring label from vulnerable namespaces
allManually remove the openshift.io/cluster-monitoring label from namespaces that have deployed ArgoCD CR instances to prevent rogue PrometheusRule creation.
oc label namespace <namespace-name> openshift.io/cluster-monitoring-
Restrict PrometheusRule creation via RBAC
allImplement RBAC policies to restrict who can create PrometheusRules in namespaces with the cluster-monitoring label.
🧯 If You Can't Patch
- Implement strict RBAC controls to limit who can deploy ArgoCD CR instances in namespaces.
- Regularly audit namespaces for the openshift.io/cluster-monitoring label and remove it from unauthorized namespaces.
- Monitor PrometheusRule creation events and alert on unexpected rule deployments.
🔍 How to Verify
Check if Vulnerable:
Check if any namespaces with ArgoCD CR instances have the openshift.io/cluster-monitoring label: oc get namespaces --selector='openshift.io/cluster-monitoring' -o json | jq '.items[].metadata.name'Check Version:
oc get csv -n openshift-gitops-operator | grep openshift-gitops-operatorVerify Fix Applied:
After patching, deploy a test ArgoCD CR instance in a namespace and verify the openshift.io/cluster-monitoring label is NOT automatically applied.📡 Detection & Monitoring
Log Indicators:
- Audit logs showing unauthorized PrometheusRule creation in namespaces with cluster-monitoring label
- Prometheus logs showing unexpected rule evaluations or errors from new rules
