Name of the Vulnerable Software and Affected Versions iframe plugin for WordPress versions up to and including 5.0

Description The issue is related to Stored Cross-Site Scripting via the plugin's shortcode(s) 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 5.0, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting contributor-level and above permissions to minimize the risk of exploitation.
