Summary

The SOGO Add Script to Individual Pages Header Footer WordPress plugin through 3.9 does not sanitise or escape the custom header/footer script values saved from its post metabox, and does not restrict them to users with the unfiltered_html capability, allowing users with contributor-level access and above to store JavaScript that executes in the browser of any administrator who reviews the post and of any visitor once the post is published.

Risk Assessment

Risk of malicious JavaScript execution in the browsers of admins and visitors, potentially leading to data theft, session hijacking, or malware distribution.

Recommendation

Update the SOGO Add Script plugin to the latest version or consider removing it if not essential. Restrict user permissions to the minimum necessary.
