Overview<\/strong><\/p>\n

Argo CD, a widely adopted GitOps continuous delivery tool for Kubernetes, has been identified to possess a significant security vulnerability labeled as CVE-2025-47933. This vulnerability, present in versions preceding 2.13.8, 2.14.13 and 3.0.4, allows for an attacker to execute arbitrary actions on behalf of the victim via the application’s API. This issue has significant implications, as it can potentially lead to full system compromise<\/a> or data leakage, affecting any organization utilizing the affected versions of Argo CD.
\nThe gravity of this vulnerability is further emphasized by its high CVSS severity<\/a> score of 9.0, indicating the potential for considerable harm and disruption if successfully exploited. Therefore, understanding the nature of CVE-2025-47933, how it operates, and how to mitigate it, is of paramount importance for any entity using Argo CD.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-47933
\nSeverity: Critical (9.0)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System compromise or data leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Argo CD | 2.13.7 and earlier
\nArgo CD | 2.14.12 and earlier
\nArgo CD | 3.0.3 and earlier<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from Argo CD’s improper filtering of URL protocols<\/a> on the repository page. This allows an attacker with the ability to edit the repository to execute a cross-site scripting<\/a> (XSS) attack. Specifically, the attacker can craft a malicious URL that, when processed by the application, executes arbitrary code<\/a> or actions on behalf of the victim.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following conceptual code illustrates how an attacker might exploit the vulnerability<\/a>:<\/p>\n

POST \/api\/v1\/repositories HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"repoURL\": \"javascript:malicious_code\",\n\"name\": \"malicious_repo\"\n}<\/code><\/pre>\n
In this example, the attacker creates a new repository with a URL containing malicious JavaScript code<\/a>. When the victim interacts with this repository, the malicious code is executed, leading to potential system compromise<\/a> or data leakage.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The most effective solution to this vulnerability is to apply the vendor-provided patches<\/a>, which have been released in Argo CD versions 2.13.8, 2.14.13, and 3.0.4. These patches address the issue by implementing proper URL protocol filtering, eliminating the potential for XSS<\/a> attacks.
\nAs a temporary mitigation, organizations can employ Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to detect and prevent potential attacks. However, these should be seen as temporary measures, and applying the vendor patches should be a priority.<\/p>\n","protected":false},"excerpt":{"rendered":"
