CVE-2026-65917: Authorization Bypass Through User-Controlled Key in usmannasir cyberpanel
CyberPanel through 1.9.1, fixed in commit b198460, contains an insecure direct object reference (IDOR) vulnerability in the IncBackups application's incremental-backup handlers (deleteBackup, fetchRestorePoints, and restorePoint) that allows authenticated panel users to access or manipulate other tenants' backup resources by supplying an attacker-controlled globally sequential IncJob integer ID that is never re-scoped to the authorized domain. Attackers can enumerate sequential backup IDs to read another tenant's backup metadata, irrecoverably delete another tenant's backup snapshots, or trigger unauthorized restoration of another tenant's backup job with root privileges.
AI Analysis
Technical Summary
CVE-2026-65917 is an IDOR vulnerability in CyberPanel through version 1.9.1 affecting the IncBackups application's incremental-backup handlers (deleteBackup, fetchRestorePoints, restorePoint). Authenticated users can supply a globally sequential IncJob integer ID that is not re-scoped to their authorized domain, enabling them to enumerate backup IDs of other tenants. This allows unauthorized access to backup metadata, irreversible deletion of backup snapshots, and triggering of unauthorized restoration of backups with root privileges. The vulnerability is addressed in a fix committed as b198460.
Potential Impact
An attacker with authenticated access to the CyberPanel can exploit this vulnerability to read sensitive backup metadata of other tenants, delete their backup snapshots irrecoverably, or restore backups with root privileges without authorization. This compromises confidentiality, integrity, and availability of backup data across tenants.
Mitigation Recommendations
A fix for this vulnerability is indicated by the commit b198460, which addresses the insecure direct object reference issue. However, explicit patch availability or vendor advisory details are not provided in the input data. Therefore, patch status is not yet confirmed — check the vendor advisory or official CyberPanel sources for current remediation guidance. Until patched, restrict authenticated user access to trusted personnel only and monitor for suspicious backup-related activities.
