Input validation vulnerability in Primary Addon for Elementor 1.5.5

The Primary Addon for Elementor is a plugin used for WordPress websites. It has a feature called Pricing Table widget that is vulnerable to a type of cyber attack called Stored Cross-Site Scripting. This is because the plugin does not properly protect against harmful code that users can input. This means that attackers with a certain level of access can insert their own malicious code into pages, which will then run whenever someone opens that page.
