Description
WordPress Plugin Frontend File Manager is prone to multiple vulnerabilities, including cross-site scripting, security bypass and arbitrary file upload vulnerabilities. Exploiting these issues may allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, to steal cookie-based authentication credentials, to perform otherwise restricted actions and subsequently change the content and title of every page and post on the blog, delete every page and post on the blog, modify the plugin�s settings, or to upload arbitrary code and run it in the context of the webserver process, which may facilitate unauthorized access or privilege escalation. WordPress Plugin Frontend File Manager version 18.2 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 18.3 or latest
