Summary

The SendPulse Email Marketing Newsletter plugin for WordPress up to version 2.2.5 has a Stored Cross-Site Scripting vulnerability via the _sp_form_code Post Meta field due to insufficient input sanitization and output escaping. Authenticated attackers with Contributor-level access and above can inject arbitrary scripts, bypassing the allow-list check.

Risk Assessment

An attacker can execute scripts in the browsers of administrators and users, potentially leading to session theft or site takeover.

Recommendation

Update the SendPulse Email Marketing Newsletter plugin to version 2.2.6 or later if available. In the meantime, restrict form editing access to trusted users only.

Original NVD description (English source)

The SendPulse Email Marketing Newsletter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via _sp_form_code Post Meta in all versions up to, and including, 2.2.5 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. Exploitation requires the attacker to create a sendpulse_form post containing a benign SendPulse loader script tag alongside arbitrary HTML (e.g., an img onerror payload), which bypasses the allow-list check and executes in the browser of any user — including administrators — who previews or views a page rendering the [sendpulse-form] shortcode.
