WordPress Plugin Vulnerabilities
Yoast SEO < 28.1 - Author+ Stored Cross-Site Scripting via Post Slug
Description
The plugin does not sanitise and escape post slugs before outputting them in generated permalinks, which could allow authenticated users with the author role and above to perform Stored Cross-Site Scripting attacks. This requires pretty permalinks to be enabled.
