CVE-2025-23216:
Argo CD vulnerability analysis and mitigation
Overview
A vulnerability (CVE-2025-23216) was discovered in Argo CD, a declarative GitOps continuous delivery tool for Kubernetes, that exposed secret values in error messages and the diff view when an invalid Kubernetes Secret resource was synced from a repository. The vulnerability was discovered on January 30, 2025, and affects versions prior to v2.13.4, v2.12.10, and v2.11.13. The issue requires write access to the repository to exploit, and once exploited, any user with read access to Argo CD can view the exposed secret data (GitHub Advisory).
Technical details
The vulnerability occurs when an invalid Kubernetes Secret resource is synced from a repository, causing secret values to be exposed in error messages and the diff view. The issue has been assigned a CVSS v3.1 score of 6.8 (Moderate) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and CWE-209 (Generation of Error Message Containing Sensitive Information) (Red Hat).
Impact
When exploited, the vulnerability allows any user with read access to Argo CD to view exposed secret data, even if they shouldn't have access to these secrets. This could lead to the unauthorized disclosure of sensitive information stored in Kubernetes Secrets (GitHub Advisory).
Mitigation and workarounds
The vulnerability has been fixed in Argo CD versions v2.13.4, v2.12.10, and v2.11.13. There are no workarounds available other than upgrading to a patched version (GitHub Advisory).
