Name of the Vulnerable Software and Affected Versions The Modern Footnotes plugin for WordPress versions up to, and including, 1.4.16

Description The issue is related to Stored Cross-Site Scripting via the plugin's shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 1.4.16, update to a version higher than 1.4.16 to resolve the issue. As a temporary workaround, consider restricting access to the shortcode feature for users with contributor-level permissions and above until a patch is available.
