Access violation vulnerability in SecuPress Free — WordPress Security 2.3.9

  • Severity: medium-risk
  • Status: Fixed
  • Publication: April 28, 2025

The free version of SecuPress, a security plugin for WordPress, has a flaw that allows unauthorized changes to be made to data. This is because a necessary check was not included in the ‘secupress_reinstall_plugins_admin_ajax_cb’ function, which affects all versions up to and including 2.3.9. As a result, attackers who are logged in with Subscriber-level access or higher can install any plugins they want.
