Privilege Escalation in VibeBP WordPress Plugin

Publication date: 2026-11-12

Last updated on: 2026-11-12

Assigner: Wordfence

Description
The VibeBP plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.9.9.8.1. This is due to the plugin allowing arbitrary user meta updates through the set_email_notification_settings() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to grant themselves administrator privileges by updating their own 'wp_capabilities' user meta value.

Executive Summary

The VibeBP WordPress plugin up to version 1.9.9.8.1 has a privilege escalation flaw. Attackers with Subscriber access or higher can exploit the set_email_notification_settings() function to update their user meta. This allows them to set their 'wp_capabilities' value to administrator, granting full admin privileges.

Detection Guidance

Check WordPress sites for the VibeBP plugin versions up to 1.9.9.8.1. Look for unauthorized changes to user meta values, especially 'wp_capabilities'. Review logs for Subscriber-level users modifying admin privileges.

Impact Analysis

If you use this plugin, an attacker could gain control of your WordPress site. They could install malicious plugins, steal data, deface your site, or use it for further attacks. Even low-privilege users like Subscribers could escalate to admin.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR and HIPAA requirements for data protection and access control. Non-compliance may result in fines or legal penalties depending on jurisdiction.

Mitigation Strategies

Update the VibeBP plugin to the latest version. Remove or disable the plugin if updates are unavailable. Audit user roles and privileges for unauthorized changes. Implement strict access controls for user meta updates.
