CVE-2026-0844 (GCVE-0-2026-0844)

Vulnerability from cvelistv5 – Published: 2026-01-28 11:23 – Updated: 2026-04-14 15:08

Title

Simple User Registration <= 6.7 - Authenticated (Subscriber+) Privilege Escalation via profile_save_field

Summary

The Simple User Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 6.7 due to insufficient restriction on the 'profile_save_field' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wp_capabilities' parameter during a profile update.

Severity

8.8 (High)
