Neuron PHP Framework SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.4)

CVE-2025-67510

The vulnerability exists in a framework designed for creating AI agents, which are commonly deployed as internet-facing services, web applications, or API endpoints to interact with external users. While the tool requires specific configuration, the product's primary role is to process untrusted input via these interfaces, making public exposure a common deployment pattern.

Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability has been identified in the Neuron PHP framework that could allow unauthorized execution of harmful database commands. This risk is amplified when AI agents built with this framework process untrusted input and are connected to databases with broad user privileges.

Malicious input can damage or delete database data.
It impacts AI agent frameworks processing external data.
Confirming exposure of AI agents to untrusted input is key.

Attack Path

How an attacker could exploit the issue

An attacker could compromise a web application or API that uses the Neuron framework to orchestrate AI agents. If the application processes untrusted input and has enabled the MySQLWriteTool, an attacker could craft malicious prompts to inject arbitrary SQL commands. This could allow them to delete, modify, or corrupt database contents, depending on the privileges granted to the database user.

An attacker needs access to an application accepting untrusted input.
The attacker triggers the vulnerability by sending crafted input.
Risk includes destructive database operations.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an attacker to execute arbitrary SQL commands on a database connected to a Neuron AI agent. When an agent processes untrusted input, malicious instructions could be injected to perform destructive actions on the database, such as deleting or altering data, or even changing user privileges, depending on the database user's permissions.

Database data and structure at risk.
Prompt injection can trigger SQL execution.
Destructive database operations could occur.

Operational Fix

Recommended remediation, mitigation, and detection steps

The "Neuron" PHP framework's MySQLWriteTool, when exposed to untrusted input and using a database user with broad privileges, presents a critical risk due to potential SQL injection. Application owners, platform teams, and security teams must collaboratively identify all instances of affected Neuron deployments. The immediate first step is to determine exposure, assess business criticality, and assign ownership for remediation, followed by a risk-based maintenance plan.

Application owners are responsible for this issue.
Verify agent exposure to untrusted input.
Plan and coordinate database-level remediation.

Frequently asked questions

What is Neuron and how is it used?

Neuron is a PHP-based framework specifically designed for building and managing AI agents. Developers use it to orchestrate how these agents interact with data, tools, and external systems, effectively serving as the infrastructure that allows AI models to perform tasks and process information within a structured application environment.

What does CWE-284 and CWE-250 mean for CVE-2025-67510?

These codes refer to Improper Access Control and Execution with Unnecessary Privileges. In this case, the MySQLWriteTool blindly executes whatever SQL instructions it receives. This vulnerability means the tool lacks the safeguards to distinguish between a legitimate request and a malicious command, allowing an AI agent to inadvertently run destructive database actions if tricked.

How does an attacker trigger this SQL injection?

The trigger occurs when an agent using the MySQLWriteTool processes malicious, untrusted input, such as a crafted prompt designed to manipulate the agent's logic. Simply having the library installed is not enough; the vulnerability is only activated if the agent is actively accepting external input and the tool is enabled to interact with the database.

Why should I care if my Neuron agent is internet-facing?

According to Halo Surface Signal, this vulnerability is particularly significant for internet-facing services. Since Neuron agents are often built to interact with external users, public-facing agents are more likely to encounter the untrusted input required to trigger this flaw. Internal tools with restricted access face a lower likelihood of targeted exploitation.

How do I start securing my applications against this risk?

Begin by auditing your projects to identify any agents using the MySQLWriteTool. The most direct resolution is to update to version 2.8.12 or higher. In the interim, ensure your database connection uses a user account restricted to the absolute minimum privileges required for the agent to function, which limits the potential damage from any injected queries.
