CVE-2023-40026

Summary

CVE-2023-40026 is a vulnerability affecting Argo CD, a continuous deployment framework for Kubernetes. In versions prior to 2.3, a specifically-crafted Helm file could leak values or files from other Helm charts by referencing them from the same repo-server. This was due to predictable Helm paths. An attacker could exploit this vulnerability by adding a Helm chart that referenced resources from predictable paths on the repo-server. Although secrets are not typically stored in these files, any values could be referenced. Argo CD has addressed this issue by randomizing Helm paths in version 2.3 and later. Users are advised to update to a supported version or take precautions such as disabling Helm chart rendering or using an additional repo-server for each Helm chart to mitigate potential exploitation.
