Executive Summary

CVE-2025-10915 is a vulnerability in the Dreamer Blog WordPress theme version 1.2 and earlier. It occurs because the theme lacks a proper capability check, allowing authenticated users with Subscriber or higher roles to install arbitrary plugins. Attackers can exploit this by sending a specially crafted POST request to the WordPress admin AJAX endpoint to install any plugin from WordPress.org without proper authorization. This is a broken access control issue. [1]

Detection Guidance

You can detect this vulnerability by monitoring for POST requests to the endpoint `wp-admin/admin-ajax.php?action=install_act_plugin_custom` with a plugin parameter specifying a plugin name. For example, inspecting web server logs or using network monitoring tools to filter for such requests can help identify exploitation attempts. A sample command using grep on server logs might be: `grep 'POST /wp-admin/admin-ajax.php?action=install_act_plugin_custom' /path/to/access.log`. Additionally, checking for unexpected plugin installations or changes in the plugins directory may indicate exploitation. [1]

Mitigation Strategies

Since no known fix is currently available, immediate mitigation steps include restricting access to the vulnerable endpoint to trusted users only, limiting user roles that can authenticate to the WordPress admin area, and monitoring for suspicious activity related to plugin installations. Additionally, consider disabling plugin installations for Subscriber+ roles or applying custom access control measures to prevent unauthorized plugin installations until an official patch is released.
