What the vulnerability does

01Description

Multiple plugins for WordPress are vulnerable to Stored Cross-Site Scripting via the plugin's bundled SimpleLightbox JavaScript library (version 2.1.5) in various versions due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for 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.
