CVE-2025-53536: Roo Code AI Agent Remote Code Execution Vulnerability

Overview

In this post, we will be discussing the CVE-2025-53536 vulnerability, a significant security flaw that affects the Roo Code AI-powered autonomous coding agent. This vulnerability is of particular concern because it allows an attacker to execute arbitrary commands on the victim’s system, potentially leading to system compromise or data leakage. Given the increasing adoption of AI-powered coding tools and their integration into the software development process, such vulnerabilities can pose a serious threat to the security of both individual developers and organizations.

Vulnerability Summary

CVE ID: CVE-2025-53536
Severity: High, CVSS v3 Score 8.1
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Roo Code | Prior to 3.22.6

How the Exploit Works

The vulnerability resides in the fact that if the victim’s settings had “Write” auto-approved, an attacker who has the ability to submit prompts to the Roo Code agent could manipulate the VS Code settings files to trigger arbitrary code execution. One way this could be achieved is through the php.validate.executablePath setting. This setting allows users to set the path for the PHP executable for syntax validation. An attacker could potentially change this path to an arbitrary command, and then create a PHP file to trigger it. This essentially opens up the entire system to the attacker, allowing them to run any command they choose.

Conceptual Example Code

Here is a conceptual example of how this vulnerability might be exploited. The attacker submits a prompt to the Roo Code agent to write the following configuration to the victim’s VS Code settings file:

{
"php.validate.executablePath": "/path/to/attacker's/arbitrary/command"
}

Next, the attacker creates a PHP file on the victim’s system:

<?php
echo "Triggering exploit...";
?>

When the PHP file is executed, the VS Code PHP validator runs the attacker’s arbitrary command, leading to potential system compromise and data leakage.

Mitigation

Users of Roo Code prior to version 3.22.6 are urged to update to the latest version to mitigate this vulnerability. As a temporary measure, users can also deploy a web application firewall (WAF) or intrusion detection system (IDS) to detect and block attempts to exploit this vulnerability. Recommended settings for these mitigation tools will depend on their specific configuration and the environment in which they are deployed.
