Exploit

WP RSS Aggregator <= 4.19.1 - Admin+ Stored Cross-Site Scripting

The WP RSS Aggregator WordPress plugin before 4.19.2 does not properly sanitise and escape the URL to Blacklist field, allowing malicious HTML to be inserted by high privilege users even when the unfiltered_html capability is disallowed, which could lead to Cross-Site Scripting issues.
