Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The WP Libre Form WordPress plugin 1.5.0.1 does not validate the type of files uploaded through its form submissions, allowing unauthenticated attackers to upload PHP files to a web-accessible location and execute them, leading to remote code execution.
