This vulnerability allows an unauthenticated attacker with direct network access to the repo-server to achieve remote code execution. By exploiting this flaw, attackers can manipulate cached data within the compromised repo-server. This manipulation can then be leveraged to deploy unauthorized and malicious Kubernetes resources to any managed clusters, potentially resulting in a complete compromise of the entire Kubernetes environment. The vulnerability, classified with a CVSS v3.1 score of 8.9 (High), stems from missing authentication for a critical function (CWE-306). Affected components include Argo CD instances and Red Hat OpenShift GitOps deployments, specifically \u003ccode\u003eargo-helm\u003c/code\u003e versions prior to 10.0.0 and certain Red Hat OpenShift GitOps and Data Foundation 4 packages.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies an internet-facing or internally accessible Argo CD repo-server instance.\u003c/li\u003e\n\u003cli\u003eThe attacker establishes network connectivity to the vulnerable Argo CD repo-server.\u003c/li\u003e\n\u003cli\u003eThe attacker exploits CVE-2026-15416, a missing authentication vulnerability, to achieve remote code execution on the repo-server process.\u003c/li\u003e\n\u003cli\u003eUsing the RCE, the attacker manipulates the repo-server's internal cached data, potentially altering configuration or deployment instructions.\u003c/li\u003e\n\u003cli\u003eThe compromised repo-server, under attacker control, initiates the deployment of malicious Kubernetes resources.\u003c/li\u003e\n\u003cli\u003eThese malicious Kubernetes resources are then provisioned onto clusters managed by the Argo CD instance.\u003c/li\u003e\n\u003cli\u003eThe deployment of malicious resources leads to a complete compromise of the targeted Kubernetes clusters, granting the attacker full control.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-15416 grants an unauthenticated attacker remote code execution capabilities on the Argo CD repo-server.
