Name of the Vulnerable Software and Affected Versions The Puzzles theme for WordPress versions up to, and including, 4.2.4

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

Recommendations For versions up to, and including, 4.2.4, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting the use of shortcodes to minimize the risk of exploitation. Additionally, limit contributor-level and above permissions to trusted users only.
