Photo Gallery by 10Web <= 1.8.18 - Authenticated (Administrator+) Stored Cross-Site Scripting via Widget
Vulnerability Description
The Photo Gallery by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widgets in versions up to, and including, 1.8.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with administrator-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. It can also be exploited with a contributor-level permission with a page builder plugin.
