The BackWPup WordPress plugin before 5.7.5 does not properly restrict access to several of its REST API routes for job, backup-destination, and backup-execution management, allowing users holding a BackWPup WordPress plugin before 5.7.5-defined, administrator-assigned limited role to create and run backup jobs and exfiltrate a full database backup to an attacker-controlled destination.
AI Analysis
Technical Summary
CVE-2026-86815 is a missing authorization vulnerability (CWE-862) in the BackWPup WordPress plugin before version 5.7.5. The plugin does not properly restrict access to certain REST API endpoints related to job, backup-destination, and backup-execution management. As a result, users assigned limited roles by the administrator can exploit these endpoints to create and execute backup jobs and send full database backups to external locations controlled by attackers.
Potential Impact
An attacker with a limited role assigned via the BackWPup plugin can bypass intended access controls to create and run backup jobs. This enables exfiltration of the entire WordPress database, potentially exposing sensitive site data and credentials.
Mitigation Recommendations
A fixed version is available at 5.7.5 or later. Users should upgrade BackWPup to version 5.7.5 or above to remediate this vulnerability. No other mitigation guidance is provided.
