At a glance
CVE-2024-7622 is a medium-severity Missing Authorization vulnerability in the Revision Manager TMC WordPress plugin, affecting versions <= 2.8.19. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.8.20; sites on affected versions should update now. Disclosed September 2024, reported by Lucio Sá.
Vulnerability Overview
The Revision Manager TMC plugin for WordPress is vulnerable to unauthorized arbitrary email sending due to a missing capability check on the _a_ajaxQuickEmailTestCallback() function in all versions up to, and including, 2.8.19. This makes it possible for authenticated attackers, with subscriber-level access and above, to send emails with arbitrary content to any individual through the vulnerable web server.
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.
CWE-862: Missing Authorization
Revision Manager TMC <= 2.8.19 carries this weakness at _a_ajaxQuickEmailTestCallback(), and reaching it takes an account at Subscriber level or above. 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 Revision Manager TMC the fix is 2.8.20: builds <= 2.8.19 are affected, anything from 2.8.20 onward is not.
Remediation
Update to version 2.8.20, 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: Revision Manager TMC 2.8.20 closes this, and updating the plugin is the step that ends it.
