WordPress Plugin Vulnerabilities
PrePost SEO <= 3.0 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not properly sanitize some of its settings, which could allow high-privilege users to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
Proof of Concept
1. Add XSS payload to plugin's "Account API key" setting: "><iframe src="<svg onload=alert(4);>"> 2. Save and see XSS exploit.
