Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Link Library WordPress plugin before 7.10.0 does not re-check the selected library's own login requirement when processing its front-end link submission, allowing unauthenticated users to submit links to a library configured to require login by reusing a form token obtained from another library that does not.
