CVE-2021-24792: Wpeden Shiny Buttons

Medium severity, CVSS 6.1. EPSS: 1.2% chance of exploitation in the next 30 days.

The Shiny Buttons WordPress plugin through 1.1.0 does not have any authorisation and CSRF in place when saving a template (wpbtn_save_template function hooked to the init action), nor sanitise and escape them before outputting them in the admin dashboard, which allow unauthenticated users to add a malicious template and lead to Stored Cross-Site Scripting issues.

Affected products

• Wpeden Shiny Buttons: up to and including 1.1.0
