WP Post Author <= 3.2.3 - Privilege Escalation

Improper Privilege Management
CVE Not available
CVSS Critical (9.8)
Publicly Published June 28, 2023
Last Updated January 22, 2024
Description

The WP Post Author plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 3.2.3. This is due to insufficient controls on the /set-user-data REST API endpoint. This makes it possible for authenticated attackers to set their user role to administrator and gain complete access to the site. Attackers can easily obtain authenticated access using the /v1/frontend/register-user REST API endpoint, even when registration is disabled on the site.
