Summary

The Simple Youtube Shortcode plugin for WordPress up to version 1.1.3 is vulnerable to Stored Cross-Site Scripting via the 'embed_youtube' shortcode. Insufficient input sanitization and output escaping on the 'id' attribute allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts that execute when a user accesses an injected page.

Risk Assessment

An attacker can inject malicious scripts that execute in the browsers of users visiting infected pages, potentially leading to session theft, account takeover, or malware distribution.

Recommendation

Update the Simple Youtube Shortcode plugin to the latest patched version. Additionally, restrict user privileges to the minimum necessary level.
