Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Document Gallery WordPress plugin through 5.1.1 does not verify the signature on one of its unauthenticated webhook endpoints when no shared secret has been configured, which is the default state, allowing unauthenticated users to replace the thumbnail image the site publishes for any document.
