What the vulnerability does
01Description
The Woodpecker for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_name' parameter of the [woodpecker-connector] shortcode in all versions up to, and including, 3.0.4 due to insufficient input sanitization and output escaping. 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.
