CVE-2021-24759
The PDF.js Viewer WordPress plugin before 2.0.2 does not escape some of its shortcode and Gutenberg Block attributes, which could allow users with a role as low as Contributor to to perform Cross-Site Scripting attacks
Does this matter?
Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.
