CVE-2021-24219 is a medium-severity Improper Access Control vulnerability in the Thrive Visual Editor WordPress plugin, affecting versions < 2.6.7.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.6.7.4; sites on affected versions should update now. Disclosed April 2021, reported by Wordfence.
Vulnerability Overview
The Thrive Optimize WordPress plugin before 1.4.13.3, Thrive Comments WordPress plugin before 1.4.15.3, Thrive Headline Optimizer WordPress plugin before 1.3.7.3, Thrive Leads WordPress plugin before 2.3.9.4, Thrive Ultimatum WordPress plugin before 2.3.9.4, Thrive Quiz Builder WordPress plugin before 2.3.9.4, Thrive Apprentice WordPress plugin before 2.3.9.4, Thrive Visual Editor WordPress plugin before 2.6.7.4, Thrive Dashboard WordPress plugin before 2.3.9.3, Thrive Ovation WordPress plugin before 2.4.5, Thrive Clever Widgets WordPress plugin before 1.57.1 and Rise by Thrive Themes WordPress theme before 2.0.0, Ignition by Thrive Themes WordPress theme before 2.0.0, Luxe by Thrive Themes WordPress theme before 2.0.0, FocusBlog by Thrive Themes WordPress theme before 2.0.0, Minus by Thrive Themes WordPress theme before 2.0.0, Squared by Thrive Themes WordPress theme before 2.0.0, Voice WordPress theme before 2.0.0, Performag by Thrive Themes WordPress theme before 2.0.0, Pressive by Thrive Themes WordPress theme before 2.0.0, Storied by Thrive Themes WordPress theme before 2.0.0, Thrive Themes Builder WordPress theme before 2.2.4 register a REST API endpoint associated with Zapier functionality. While this endpoint was intended to require an API key in order to access, it was possible to access it by supplying an empty api_key parameter in vulnerable versions if Zapier was not enabled. Attackers could use this endpoint to add arbitrary data to a predefined option in the wp_options table.
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 privileges on the target site, and no interaction from a victim user.
CWE-284: Improper Access Control
Reaching this weakness in Thrive Visual Editor < 2.6.7.4 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.
Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Thrive Visual Editor the fix is 2.6.7.4: builds < 2.6.7.4 are affected, anything from 2.6.7.4 onward is not.
Remediation
Update to version 2.6.7.4, 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: Thrive Visual Editor 2.6.7.4 closes this, and updating the plugin is the step that ends it.
