Responsive Pricing Table < 5.1.13 - Authenticated (Author+) Stored Cross-Site Scripting

Description

The Responsive Pricing Table plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'plan_icons' parameter in all versions up to, and including, 5.1.12 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
