WordPress Plugin Vulnerabilities
Easy Accept Payments for PayPal < 4.9.10 - Contributor+ Stored XSS
Description
The plugin does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.
Proof of Concept
