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 affecting CyberPanel through version 1.9.1 in the IncBackups application's incremental-backup handlers (deleteBackup, fetchRestorePoints, and restorePoint). The issue arises because the globally sequential IncJob integer ID used to identify backup jobs is not properly scoped to the authenticated user's domain, allowing authenticated panel users to enumerate and manipulate backup resources belonging to other tenants. This can lead to unauthorized reading of backup metadata, irreversible deletion of backup snapshots, and unauthorized restoration of backups with root privileges. The vulnerability has a CVSS 4.0 score of 8.7 (high severity).
Potential Impact
Exploitation allows authenticated users to bypass authorization controls and access or manipulate backup resources of other tenants. This includes reading sensitive backup metadata, deleting backups irrecoverably, and restoring backups with root privileges, potentially compromising tenant data integrity and confidentiality.
Mitigation Recommendations
A fix for this vulnerability is available and was implemented in commit b198460. Users should upgrade CyberPanel to a version that includes this fix (versions later than 1.9.1). Since no official patch link or advisory is provided, verify the update from the vendor or trusted source before applying. Patch status is not yet confirmed in a vendor advisory; check the vendor's official channels for current remediation guidance.
