Sources and claim methodology

  • GitHub security advisorygithub.com
  • Source referencevulncheck.com
Upstream source description

Craft CMS versions before 5.10.11 fail to validate admin status in the actionGetPasswordResetUrl endpoint, allowing non-admin users with administrateUsers permission to mint password reset URLs for administrator accounts. Attackers can generate a valid reset URL for any admin user and set a new password via actionSetPassword, which validates only the verification code without checking the caller's session, enabling complete control-panel takeover.
