Name of the Vulnerable Software and Affected Versions: Display Post Metadata WordPress plugin versions prior to 1.5.0

Description: The issue concerns the Display Post Metadata WordPress plugin, where a shortcode used to print out custom fields does not properly sanitise or escape the content. This could allow users with a role as low as Contributor to perform Cross-Site Scripting attacks.

Recommendations: For versions prior to 1.5.0, update to version 1.5.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the shortcode that prints custom fields to minimize the risk of exploitation.
