WordPress Plugin Vulnerabilities
Great Quotes <= 1.0.0 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not sanitise and escape the Quote and Author fields of its Quotes, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed.
Proof of Concept
Add/edit a Quote and put the following payload in the "Quote" and "Author" fields: <img src onerror=alert(/XSS/)>
