At a glance
CVE-2025-6574 is a high-severity Authorization Bypass Through User-Controlled Key vulnerability in the Service Finder Bookings WordPress plugin, affecting versions < 6.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 6.1; sites on affected versions should update now. Disclosed October 2025, reported by Thái An.
Vulnerability Overview
The Service Finder Bookings plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and excluding, 6.1. This is due to the plugin not properly validating a user's identity prior to updating their details like email. This makes it possible for authenticated attackers, with subscriber-level access and above, to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Service Finder Bookings < 6.1 takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Service Finder Bookings the fix is 6.1: builds < 6.1 are affected, anything from 6.1 onward is not.
Remediation
Update to version 6.1, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Service Finder Bookings 6.1 closes this, and updating the plugin is the step that ends it.
