WSMS (formerly WP SMS) – SMS & MMS Notifications with OTP and 2FA for WooCommerce < 7.1.1 - Authenticated (Administrator+) Stored Cross-Site Scripting

Description

The WSMS (formerly WP SMS) – SMS & MMS Notifications with OTP and 2FA for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 7.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
