CVE-2025-47933: 
Argo CD vulnerability analysis and mitigation

Argo CD, a declarative GitOps continuous delivery tool for Kubernetes, was found to contain a critical cross-site scripting (XSS) vulnerability identified as CVE-2025-47933. The vulnerability was disclosed on May 28, 2025, affecting versions prior to 2.13.8, 2.14.13, and 3.0.4. This security flaw exists in the repository page functionality where improper filtering of URL protocols could allow attackers to perform malicious actions (GitHub Advisory, NVD).

The vulnerability stems from improper URL protocol filtering in the repository page component, specifically in the ui/src/app/shared/components/urls.ts file. The issue received a CVSS v3.1 base score of 9.0 (Critical) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H. The technical root cause involves the repoUrl function not validating URL protocols properly, allowing potential injection of javascript: URLs that can be exploited for XSS attacks (GitHub Advisory, Wiz).

The vulnerability enables attackers with repository editing permissions to perform arbitrary actions on behalf of victims through the API. These actions can include creating, modifying, and deleting Kubernetes resources. The high severity rating reflects the potential for significant system compromise through the exploitation of this vulnerability (GitHub Advisory, Wiz).

The vulnerability has been patched in Argo CD versions 2.13.8, 2.14.13, and 3.0.4. The fix includes implementing proper URL validation that returns null if validation fails. For unpatched systems, there are no effective workarounds other than relying on browser-based URL filtering (GitHub Advisory, NVD).
