CVE-2026-28264 is a low-severity Incorrect Permission Assignment for Critical Resource (CWE-732) vulnerability in Dell Powerprotect Data Manager. Its CVSS base score is 3.3 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Why these techniques?
Incorrect permissions on critical resource directly enable low-privileged local read access to sensitive data on the system.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly counters CWE-732 by requiring that only the minimum necessary permissions are granted to the Agent Service's critical resources, blocking low-privileged local access to exposed information.
Enforces the system's access-control policy on the affected resources so that an incorrect permission assignment cannot be exercised by an unauthorized local process or user.
Mandates applying and verifying secure configuration settings (including file/registry permissions) for the Agent Service, preventing the vulnerable default or mis-assigned rights from remaining in place.

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.
Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.
Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.
Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.
Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.
By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
