WordPress Plugin Vulnerabilities
SendPress Newsletters <= 1.23.11.6 - Admin+ Stored XSS via Settings
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
Proof of Concept
1. Click SendPress in the Admin menu (which is available on the left side) 2. Go to the Settings=>Advanced, In the Optional Settings of 'Read More override' paramete add the payload: `"/><img src=x onerror=prompt(document.cookie)>` 3. Save and reload to see XSS.
