Summary

CVE-2023-40026 is a vulnerability in Argo CD, a declarative continuous deployment framework for Kubernetes. The vulnerability affects Argo CD versions prior to 2.3, starting at least in v0.1.0, but likely in any version using Helm before 2.3. By using a specifically-crafted Helm file, an attacker could reference external Helm charts handled by the same repo-server to leak values or files from the referenced Helm Chart. This could be done by adding a Helm chart that referenced Helm resources from predictable paths. While generally secrets are not stored in these files, it was possible to reference any values from these charts. The vulnerability was fixed in Argo CD 2.3 and subsequent versions by randomizing Helm paths. Organizations using Argo CD 2.3 or below are advised to update to a fixed version to mitigate the potential danger posed by this vulnerability.
