Name of the Vulnerable Software and Affected Versions: Advanced WordPress Backgrounds plugin for WordPress versions up to, and including, 1.12.3

Description: The issue is related to Stored Cross-Site Scripting via the imageTag parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page.

Recommendations: For versions up to, and including, 1.12.3, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the imageTag parameter to minimize the risk of exploitation.
