Privilege Escalation Vulnerability in AI Engine WordPress Plugin, Allows Subscriber-Level Account Takeover 

Summary :Security Advisory: A critical privilege escalation vulnerability (CVE-2025-5071) was discovered in the AI Engine WordPress plugin, allowing subscriber-level users to gain administrator privileges when the MCP (Model Context Protocol) module is enabled.

OEM WordPress 
Severity High 
CVSS Score 8.8 
CVEs CVE-2025-5071 
POC Available Yes 
Actively Exploited No 
Exploited in Wild No 
Advisory Version 1.0 

Overview 

The AI Engine plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the ‘Meow_MWAI_Labs_MCP::can_access_mcp’ function in versions 2.8.0 to 2.8.3.

This makes it possible for authenticated attackers, with subscriber-level access and above, to have full access to the MCP and run various commands like ‘wp_create_user’, ‘wp_update_user’ and ‘wp_update_option’, which can be used for privilege escalation, and ‘wp_update_post’, ‘wp_delete_post’, ‘wp_update_comment’ and ‘wp_delete_comment’, which can be used to edit and delete posts and comments.

Vulnerability Name CVE ID Product Affected Severity Fixed Version 
​Privilege Escalation Vulnerability  CVE-2025-5071 AI Engine WordPress Plugin  High  2.8.4 

Technical Summary 

AI Engine is a WordPress plugin that recently introduced support for MCP (Model Context Protocol), which allows AI agents – such as Claude or ChatGPT – to control and manage the WordPress website by executing various commands, managing media files, editing users, and performing complex tasks more reliably than through standard APIs.

The vulnerability stems from insufficient authorization checks in the can_access_mcp () function within the plugin, enabling any authenticated (logged-in) user to bypass Bearer Token validation and access MCP endpoints.

This access can be exploited to escalate user privileges by executing commands such as wp_update_user, ultimately leading to full site compromise. 

CVE ID System Affected  Vulnerability Details Impact 
  CVE-2025-5071  WordPress with AI Engine Plugin 2.8.0–2.8.3 The can_access_mcp() function incorrectly grants MCP endpoint access to all logged-in users. Even when Bearer Token authentication is enabled, lack of empty value checks in the token validation logic allows privilege escalation.  Complete site compromise 

Remediation: 

  • Immediate Action: Update the AI Engine plugin to version 2.8.4 or later. 
  • Configuration Check: Ensure that MCP and Dev Tools modules remain disabled unless it’s necessary. 

Conclusion: 
The CVE-2025-5071 vulnerability in the AI Engine WordPress plugin highlights the potential risks when advanced modules like MCP are misconfigured.

Even though the feature is disabled by default, sites that have enabled it become susceptible to complete takeover by authenticated users.

Website administrators are urged to update to version 2.8.4 immediately and verify that security best practices are enforced to prevent such escalations. With over 100,000 active installations, this flaw presents a significant risk to the WordPress ecosystem if left unpatched.

Critical Chrome Vulnerability (CVE-2025-2783) Exploited in Cyber-Espionage Campaign

OEMGoogle Chrome
SeverityHigh
CVSS8.3
CVEsCVE-2025-2783
Exploited in WildYes
Patch/Remediation AvailableYes
Advisory Version1.0

Overview

The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent advisory regarding the critical zero-day vulnerability, CVE-2025-2783, in Google Chrome and other Chromium-based browsers on Windows. This vulnerability is actively exploited in the wild and has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog, urged immediate patching to prevent security breaches and unauthorized system access.

Vulnerability NameCVE IDProduct AffectedSeverityFixed Version
  Google Chromium Mojo Sandbox Escape Vulnerability  CVE-2025-2783  Google Chrome  High  134.0.6998.117/.118

Technical Summary

This high-severity vulnerability found in the Mojo framework of Chromium-based browsers including Google Chrome, Microsoft Edge, and Opera, Brave etc. The vulnerability originates from a logic error that results in an incorrect handle being provided under certain conditions. This flaw allows attackers to bypass Chrome’s sandbox protections and potentially execute arbitrary code on the affected system.

Security researchers from Kaspersky discovered this zero-day vulnerability as part of an advanced cyber-espionage campaign dubbed “Operation ForumTroll.” The attack campaign targeted media outlets, educational institutions, and government organizations in Russia through highly personalized phishing emails.

The exploit chain is particularly dangerous because it requires minimal user interaction. Victims only need to click on a malicious link in a phishing email, after which the attack executes automatically without any additional action from the user. Once triggered, the exploit allows attackers to escape Chrome’s sandbox environment, leading to remote code execution and possible system compromise.

    CVE-2025-2783    Google Chrome (Windows)    Incorrect handle provided in Mojo, allowing sandbox escape  Remote code execution, System Compromise

Remediation:

  • Google Chrome Patch Released: Google has released security updates in Chrome versions 134.0.6998.177/.178 to address this vulnerability. Users should update immediately.

General Recommendations:

  • Enable Automatic Updates: Ensure automatic updates are enabled in Google Chrome and other Chromium-based browsers to receive future security patches promptly.
  • Phishing Awareness Training: Organizations should educate employees on identifying and avoiding phishing emails to prevent exploitation.
  • Endpoint Security Measures: Deploy endpoint detection and response (EDR) solutions to monitor and mitigate potential threats.
  • CISA Compliance for Federal Agencies: Federal agencies must adhere to CISA’s Binding Operational Directive (BOD) 22-01 to address known exploited vulnerabilities promptly.

Conclusion:

The exploitation of CVE-2025-2783 demonstrates the ongoing threat posed by sophisticated cyber-espionage activities.  Google has responded swiftly with a patch, and users are strongly advised to update their browsers immediately. Organizations should remain vigilant against phishing attempts and enhance their cybersecurity posture to mitigate similar threats in the future.
