Name of the Vulnerable Software and Affected Versions Flexmls® IDX Plugin versions up to, and including, 3.14.27

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

Recommendations For Flexmls® IDX Plugin versions up to, and including, 3.14.27, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'idx frame' shortcode. As a temporary workaround, consider restricting access to the 'idx frame' shortcode for users with contributor-level access and above until a patch is available.
