Woodpecker for WordPress Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Woodpecker for WordPress plugin, affecting all versions up to and including 3.0.4. The issue arises from inadequate input sanitization and output escaping in the 'form_name' parameter of the [woodpecker-connector] shortcode. This vulnerability allows authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access or higher can create or edit a page and insert the [woodpecker-connector] shortcode. The user must include a 'form_name' parameter that contains the script to be injected. Once the page is saved and viewed, the injected script will execute.
