Themeflection Numbers <= 1.8.1 - Authenticated(Subscriber+) Privilege Escalation via tf_numb_save_licenses

Missing Authorization
CVE CVE-2023-0889

Researcher dc11


The Themeflection Numbers plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the tf_numb_save_licenses function in versions up to, and including, 1.8.1. This makes it possible for authenticated attackers with subscriber-level capabilities to update arbitrary site options, which can lead to privilege escalation. Version 2.0.0 introduced a partial patch which prevented privilege escalation but still potentially allowed data modification.
