Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Essential Real Estate WordPress plugin before 5.3.6 does not verify that the recipients it allows for its contact email action are legitimate, allowing users with the self-registered Customer role to add any address to that allowlist so that unauthenticated users can then send emails with attacker-controlled content to it through the site.
