CVE-2025-32432: Remote Code Execution Vulnerability in Craft CMS

Overview

Craft, a popular CMS widely used for creating custom digital experiences on the web, has been identified to contain a high-impact, low-complexity vulnerability that permits remote code execution. This vulnerability, labeled as CVE-2025-32432, affects multiple versions of the Craft CMS and can potentially lead to a complete system compromise or data leakage. Given the widespread use of Craft CMS, the impact of this vulnerability can be far-reaching, affecting web developers, businesses, and individual users alike.

Vulnerability Summary

CVE ID: CVE-2025-32432
Severity: Critical (CVSS 10.0)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Craft CMS | 3.0.0-RC1 to 3.9.14
Craft CMS | 4.0.0-RC1 to 4.14.14
Craft CMS | 5.0.0-RC1 to 5.6.16

How the Exploit Works

The vulnerability stems from the Craft CMS’s improper handling of certain data inputs, which can be manipulated to execute arbitrary code on the server running the CMS. An attacker can exploit this flaw by sending a specially crafted payload to the CMS, causing the system to execute the attacker’s code. Because no user interaction or special privileges are required to exploit this vulnerability, it can be taken advantage of by any attacker with access to the network.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /vulnerable-endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"malicious_payload": "'; DROP TABLE users; --"
}

In this example, a malicious payload is sent to a vulnerable endpoint within the Craft CMS. The payload contains a SQL injection command that, when executed, deletes the users table from the database.
Please note that this is a conceptual example and actual payloads may differ. However, the overarching idea remains the same – a malformed input is used to trigger arbitrary code execution on the server.

Mitigation

The vendor has released patches to address this vulnerability in versions 3.9.15, 4.14.15, and 5.6.17 of Craft CMS. As immediate action, users are strongly advised to apply these patches. If patching is not immediately possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate the risks temporarily. These systems can block or alert on suspicious payloads, providing a layer of defense against the exploit.
