Short explanation
The Kali Forms plugin before version 2.4.30 does not perform a capability check on its test-email handler. Relying solely on a nonce available to any logged-in user, low-privileged users such as Subscribers can force the site to send emails to arbitrary recipients with a spoofed sender address.
It allows low-privileged users to send spoofed emails to arbitrary recipients via the site, creating risks for phishing or malicious communication campaigns.
What should be done?
- Follow vendor advisories and updates
- Update the plugin from vulnerable versions
- Review user roles and privileges
