At a glance
CVE-2024-38695 is a medium-severity Missing Authorization vulnerability in the WP GoToWebinar WordPress plugin, affecting versions <= 15.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 15.7; sites on affected versions should update now. Disclosed July 2024, reported by Majed Refaea.
Vulnerability Overview
The WP GoToWebinar plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wp_gotowebinar_get_access_and_refresh_token_call() function in versions up to, and including, 15.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to refresh a token.
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
WP GoToWebinar <= 15.6 carries this weakness at wp_gotowebinar_get_access_and_refresh_token_call(), and reaching it 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 WP GoToWebinar the fix is 15.7: builds <= 15.6 are affected, anything from 15.7 onward is not.
Remediation
Update to version 15.7, 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: WP GoToWebinar 15.7 closes this, and updating the plugin is the step that ends it.
