High CVSS 8.9
CVE-2026-15416
NVD analysis in progress
A flaw was identified in Argo CD, the GitOps engine used by Red Hat OpenShift GitOps, that could allow an unauthenticated attacker with network access to the Argo CD repo-server to achieve remote code execution. Under certain conditions, the attacker may then manipulate cached data to deploy malicious Kubernetes resources to managed clusters, potentially resulting in complete cluster compromise.
What this means
- Exposure
- Exploitable from the adjacent network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- A sensitive function is reachable with no authentication at all.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
