Detailsinfo

A vulnerability, which was classified as critical, was found in Red Hat OpenShift GitOps (version unknown). This affects an unknown function of the component Repo-Server. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at access.redhat.com. This vulnerability is uniquely identified as CVE-2026-15416 since 07/10/2026. The exploitability is told to be easy.
