Last updated on: 2026-08-31

Assigner: VulnCheck

Description
Keep Backup Daily plugin for WordPress before 2.1.4 contains a sensitive information exposure vulnerability that allows unauthenticated attackers to trigger a full MySQL database dump by accessing the publicly exposed `kbd_cron_process` parameter without authentication. Attackers can predict the partially predictable dump filename based on the database name, a limited random range, and the current Unix timestamp to download the generated backup from the publicly accessible uploads directory.

Executive Summary

This vulnerability in the Keep Backup Daily WordPress plugin before version 2.1.4 allows unauthenticated attackers to trigger a full MySQL database dump by accessing the publicly exposed kbd_cron_process parameter without authentication. The dump filename is partially predictable, combining the database name, a limited random range, and the current Unix timestamp, enabling attackers to download the backup from the publicly accessible uploads directory.

Detection Guidance

Check if the Keep Backup Daily plugin is installed and verify its version. If it is below 2.1.4, the vulnerability likely exists. Inspect web server access logs for requests to the kbd_cron_process parameter or unusual database dump file downloads in the uploads directory.

Impact Analysis

This vulnerability can expose sensitive information from your WordPress database, including user credentials, personal data, and other confidential content. Attackers could use this to steal data, gain unauthorized access to your site, or perform further attacks. The impact severity is high due to the potential for full database exposure without authentication.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing personal and sensitive data. GDPR requires protecting personal data, and HIPAA mandates safeguarding protected health information. A data breach due to this flaw may result in legal penalties, fines, and reputational damage for affected organizations.

Mitigation Strategies

Immediately update the Keep Backup Daily plugin to version 2.1.4 or later. If an update is unavailable, disable the plugin until a patch is released. Review and restrict access to the uploads directory to prevent unauthorized file downloads.
