Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Smart Post WordPress plugin before 4.0.8 does not check the type, ownership or status of the post it is asked to duplicate, allowing users with contributor privileges and above to copy any private or password protected post into a draft of their own and read its content and metadata.
