Name of the Vulnerable Software and Affected Versions: The All in One SEO – Powerful SEO Plugin to Boost SEO Rankings & Increase Traffic plugin for WordPress versions up to, and including, 4.8.1.1

Description: The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping in the post Meta Description and Canonical URL parameters. 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 versions up to, and including, 4.8.1.1, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the post Meta Description and Canonical URL parameters to minimize the risk of exploitation.
