Miraculous Core Plugin Privilege Escalation Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-49388

The vulnerability affects a WordPress plugin. WordPress plugins are commonly deployed as part of public-facing web applications. Because these applications are designed to be accessed via the internet, the plugin's code and its associated functionality are typically exposed to remote users, making this a likely internet-facing attack surface.

Horizon Alert

Summary of the vulnerability and why it matters

This critical vulnerability in the Miraculous Core Plugin could allow unauthorized users to gain elevated privileges, potentially impacting systems that rely on this plugin. The primary concern is to confirm if your organization utilizes this specific plugin and to assess any exposure.

  • Plugin allows unauthorized privilege escalation.
  • Affects public-facing web applications.
  • Confirm relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending a specially crafted request to a vulnerable instance of the Miraculous Core Plugin. This could allow them to gain elevated privileges, potentially leading to complete system compromise.

  • No authentication or privileges required.
  • Triggered via network request to the plugin.
  • Allows significant privilege escalation.

Live Threat

Current exploitation, exposure, and threat context

A privilege escalation vulnerability in the Miraculous Core Plugin could allow an unauthenticated attacker to gain elevated privileges on a system. This could occur when the plugin is used in a WordPress environment that is accessible over the network, potentially leading to unauthorized control or modification of system data and behavior.

  • System data and configurations.
  • Via network, unauthenticated access.
  • Unauthorized system control.

Operational Fix

Recommended remediation, mitigation, and detection steps

This critical vulnerability in the Miraculous Core Plugin impacts privilege escalation. The first practical step is for the application owner or platform team to identify all instances of the plugin, determine their reachability and business criticality, and then coordinate remediation based on risk.

  • Application owners should own this issue.
  • Verify plugin reachability and business criticality.
  • Plan remediation during maintenance windows.

Frequently asked questions

What is the Miraculous Core Plugin?

The Miraculous Core Plugin is a component built for WordPress environments. Plugins like this extend the core functionality of a website, enabling specific features or administrative tools. This plugin is used to manage system operations within WordPress, meaning its code runs directly on the server hosting the site.

What does CWE-266 mean for CVE-2025-49388?

CWE-266 refers to Incorrect Privilege Assignment. In the context of this CVE, it means the plugin fails to properly verify or restrict a user's rights. Instead of maintaining standard access controls, the software incorrectly grants higher-level permissions to users, potentially allowing a standard visitor to act as an administrator.

How is this vulnerability triggered?

An attacker triggers this bug by sending a specifically formatted network request to the WordPress instance where the plugin is active. It does not require the attacker to have an existing account or pre-existing login credentials. Importantly, standard, legitimate traffic to your website does not trigger this issue; it requires a malicious request specifically designed to exploit the privilege assignment logic.

Why is this CVE considered relevant to my setup?

Halo Surface Signal classifies this as likely internet-facing because it is a WordPress plugin. Since WordPress sites are typically built to be accessible to the public, the plugin code is exposed to remote users over the network. If your instance is reachable from the internet, an attacker can send requests to the plugin from anywhere, making it a priority for assessment.

Do I need to take action if I use this plugin?

Yes. Your first step should be to create an inventory of all WordPress sites to identify if and where this plugin is installed. Once you have identified affected instances, evaluate their importance to your operations. Coordinate with your team to plan a security update or removal during your next scheduled maintenance window to mitigate the risk of unauthorized system control.
