Advisory

Multiple plugins for WordPress are vulnerable to Stored Cross-Site Scripting in various versions due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
