Better Find and Replace < 1.7.7 - Admin+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
