Name of the Vulnerable Software and Affected Versions The Markup (JSON-LD) structured in schema.org WordPress plugin versions 4.8.1 and earlier

Description The issue concerns a failure to validate and escape certain shortcode attributes in the plugin, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks. This occurs when the shortcode is embedded in a page or post and the attributes are outputted without proper validation and escaping.

Recommendations For versions 4.8.1 and earlier, update to a version that addresses this issue. As a temporary workaround, consider restricting the use of shortcodes by users with the contributor role and above until a patch is available.
