CVE-2025-47933 in argocd
Summary
by MITRE • 05/29/2025
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.13.8, 2.14.13, and 3.0.4, an attacker can perform arbitrary actions on behalf of the victim via the API. Due to the improper filtering of URL protocols in the repository page, an attacker can achieve cross-site scripting with permission to edit the repository. This issue has been patched in versions 2.13.8, 2.14.13, and 3.0.4.

The vulnerability identified as CVE-2025-47933 affects Argo CD, a widely-used declarative GitOps continuous delivery tool for Kubernetes environments. This security flaw exists in versions prior to 2.13.8, 2.14.13, and 3.0.4, representing a critical risk to organizations relying on GitOps practices for their containerized application deployments. The vulnerability stems from inadequate validation of URL protocols within the repository management interface, creating a pathway for malicious actors to exploit the system through API interactions. This issue falls under the CWE-79 category of Cross-Site Scripting, specifically demonstrating how improper input validation can lead to unauthorized code execution within the context of a victim's session.
The technical implementation of this vulnerability occurs through the repository page's insufficient filtering mechanisms for URL protocols, allowing attackers to inject malicious scripts that can execute with the privileges of users who interact with the compromised repository. When an attacker crafts a malicious URL containing script code within the repository configuration, the system fails to properly sanitize the input before rendering it in the web interface. This allows the script to execute in the victim's browser context, enabling the attacker to perform arbitrary actions on behalf of the legitimate user. The vulnerability specifically impacts users with edit permissions to repositories, as the XSS payload can leverage these elevated privileges to manipulate the GitOps configuration and potentially compromise the entire deployment pipeline.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to manipulate the GitOps delivery process that governs Kubernetes deployments. An attacker with access to the repository editing functionality can potentially modify deployment manifests, inject malicious code into the pipeline, or redirect deployment targets to compromised systems. This represents a significant threat to the integrity and security of continuous delivery workflows, as the GitOps model relies on the trustworthiness of repository configurations. The vulnerability undermines the fundamental security assumptions of the GitOps approach, where changes are supposed to be traceable and secure through proper authentication and authorization controls. Organizations using Argo CD for production deployments face potential compromise of their entire Kubernetes infrastructure if this vulnerability is exploited.
Mitigation strategies for CVE-2025-47933 require immediate patching of affected Argo CD installations to versions 2.13.8, 2.14.13, or 3.0.4, which contain the necessary input validation fixes. Administrators should also implement additional security measures including regular monitoring of repository configurations, implementing strict access controls with the principle of least privilege, and conducting thorough security reviews of all GitOps configurations. Network-level protections such as web application firewalls and content security policies can provide additional defense-in-depth layers. The vulnerability demonstrates the importance of proper input validation in web applications, particularly those handling user-provided URLs and configuration data, and aligns with ATT&CK technique T1566.001 for credential access through web application attacks. Organizations should also consider implementing automated security scanning tools that can detect similar input validation issues in their GitOps configurations and other deployment automation tools.
