Name of the Vulnerable Software and Affected Versions rexCrawler plugin for WordPress versions prior to 1.0.16

Description The rexCrawler plugin for WordPress is susceptible to Reflected Cross-Site Scripting through the url and regex parameters within the search-pattern tester page. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary web scripts. Successful exploitation requires tricking an administrator into performing an action, such as clicking a malicious link. This issue specifically impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update the rexCrawler plugin to version 1.0.16 or later.
