At a glance

CVE-2024-12259 is a high-severity Missing Authorization vulnerability in the RepairBuddy WordPress plugin, affecting versions <= 3.8120. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 3.8122; sites on affected versions should update now. Disclosed December 2024, reported by Thanh Nam Tran.

Vulnerability Overview

The CRM WordPress Plugin – RepairBuddy plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.8120. This is due to the plugin not properly validating a user's identity prior to updating their email through the wc_update_user_data AJAX action. 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-862: Missing Authorization

Reaching this weakness in RepairBuddy <= 3.8120 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For RepairBuddy the fix is 3.8122: builds <= 3.8120 are affected, anything from 3.8122 onward is not.

Remediation

Update to version 3.8122, 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: RepairBuddy 3.8122 closes this, and updating the plugin is the step that ends it.
