Summary

The Doppler Forms WordPress plugin through 2.5.1 registers an AJAX action install_extension without verifying user capabilities or using a nonce. As a result, any authenticated user — including those with the Subscriber role — can install and activate additional Doppler Forms WordPress plugin through 2.5.1 (limited to those whitelisted by the main Doppler Forms WordPress plugin through 2.5.1).

Risk Assessment

Even a user with the lowest privileges (Subscriber) can install and activate plugins, potentially leading to unauthorized site changes and potential privilege escalation.

Recommendation

Update the Doppler Forms plugin to a version newer than 2.5.1 or remove it if unused. Consider limiting the ability to register new users.
