MEDIUM 5.1EPSS 0.14%

Does this matter?

Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

Simple Link Directory through 9.0.4 echoes embed shortcode attributes into HTML data attributes without escaping in the embedder template. Attackers with contributor access can craft a shortcode attribute that injects an event handler executing in a viewer's browser.
