Assumption Retired Role-based access controls within backup platforms constrain privilege amplification.

CVE-2025-59470 (CVSS 9.0) and CVE-2025-55125 (CVSS 7.2) disclosed January 6, 2026 demonstrate that Veeam Backup & Replication backup operators and tape operators can escalate to postgres user or root through malicious parameters and configuration files. Veeam downgraded the critical rating because "these roles are considered highly privileged and should be protected as such." That statement inverts the security model: the roles exist to constrain privilege, not to require additional privilege protection.

Insight Backup platforms operate with systemic privilege over production systems and data integrity. Role-based access controls inside those platforms are only meaningful if they prevent privilege amplification within the platform itself. The disclosed vulnerabilities demonstrate that this condition does not hold. This judgment applies to backup systems that rely on internal role separation as a containment control, independent of vendor.

Unresolved Edge If backup operator roles require the same protection as administrator roles, what function do they serve? Role-based access control assumes differentiated privilege. When every role with operational access can escalate to root, the role model is cosmetic.
