What is CVE-2026-2515?

The Hostinger Reach plugin for WordPress has a vulnerability that allows authenticated attackers with Subscriber-level access or higher to alter data within the plugin. This occurs due to a missing capability check in the 'handle_ajax_action' function, specifically when utilizing the 'hostinger_reach_connection_notice_action' action. The exploit is possible only when the plugin is not connected to a site, meaning no API key value exists in the database. Attackers can leverage this vulnerability to update critical settings, including the API key, thereby posing a significant risk to plugin integrity.

Affected Version(s)
