Executive Summary

This vulnerability exists in the Call Now Button WordPress plugin (up to version 1.5.3) where there is a missing capability check in the activate function. This allows authenticated users with Subscriber-level access or higher to link the plugin to their own nowbuttons.com account and add malicious buttons to the site. It only affects fresh installs where the plugin has not been configured with an API key.

Impact Analysis

An attacker with Subscriber-level access can exploit this vulnerability to add malicious buttons to your WordPress site via the Call Now Button plugin. This could lead to unauthorized modifications on your site, potentially misleading users or causing other security issues.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Call Now Button plugin to a version later than 1.5.3 where the issue is fixed. If updating is not possible, restrict Subscriber-level access and above from activating or configuring the plugin until a patch is applied. Additionally, verify that the plugin has been configured with an API key to prevent exploitation on fresh installs.
