CVE-2026-12195

myVesta · vesta

The myVesta control panel contains an authenticated remote code execution vulnerability due to improper neutralization of special elements in OS commands.

Executive summary

An authenticated remote code execution vulnerability in myVesta allows attackers with low-level privileges to gain unauthorized system access.

Vulnerability

This is an OS command injection (CWE-78) vulnerability that can be exploited by an authenticated attacker. By injecting malicious input, an attacker can execute arbitrary code on the underlying server hosting the control panel.

Business impact

This vulnerability carries a CVSS score of 8.5, indicating a high risk of server compromise. Successful exploitation grants an attacker the ability to execute code with the privileges of the web application, leading to potential data theft, server-wide malware installation, or full administrative takeover of the hosting environment.

Remediation

Immediate Action: Update the myVesta installation to the latest version or apply the specific commit referenced in the vendor documentation to remediate the command injection vector.

Proactive Monitoring: Inspect system logs for suspicious shell activity or unexpected process spawning initiated by the web service user.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block OS command injection attempts in HTTP requests.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Remote code execution vulnerabilities are critical. Administrators should treat this as a priority update, especially for internet-facing installations. Ensure that all web application components are updated and that the underlying OS is hardened to limit the impact of a potential compromise.
