Research Description: The rexCrawler plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'url' and 'regex' parameters in the search-pattern tester page in all versions up to, and including, 1.0.15 due to insufficient input sanitization and output escaping.

Affected versions: max 1.0.15.
