Input validation vulnerability in SlingBlocks – Gutenberg Blocks by FunnelKit (Formerly WooFunnels) 1.6.0

The SlingBlocks plugin for WordPress, created by FunnelKit (previously known as WooFunnels), has a security vulnerability that allows for Stored Cross-Site Scripting. This means that certain features in the plugin, specifically the Countdown block, do not properly protect against harmful code being added to a website. As a result, someone with contributor-level access or higher can add code that will run when a user visits a certain page.
