The Services Section Block – Showcase Service Details in Grid or Columns plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'link' Block Attribute in all versions up to, and including, 1.4.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload persists inside HTML comments in post content, bypassing wp kses post sanitization at save time, and executes via both the primary service link anchor and a secondary title-wrapped anchor when the linkIn option is set to 'title'.
