Summary

CVE-2026-94425 is a critical-severity Incorrect Privilege Assignment (CWE-266) vulnerability. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Abuse Elevation Control Mechanism (T1548); ranked at the 5th 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-16 (Security and Privacy Attributes) and AC-2 (Account Management) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Binding security attributes to subjects/objects supplies the mechanism needed to track and enforce privileges correctly.

Account management defines and authorizes the exact privileges granted to each account or role.

Requiring explicit access-control decisions ensures privileges are evaluated rather than assumed or omitted.

Enforces only the authorizations that were assigned, so correct assignment is a prerequisite.

Separation of duties constrains which privilege combinations may be assigned to any actor.

Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

PR.AA-05 enforces least privilege/SoD and periodic reviews that directly remove most privilege-assignment defects, yet CWE-269 also covers escalation paths and role design outside a single access-management control.

PR.AA-01 partial match
prevents

PR.AA-01 supplies credential/identity lifecycle support that can reduce some privilege-assignment errors but does not itself assign, modify, or check privileges, leaving most of CWE-269's risk unaddressed.

PR.PS-01 partial match
prevents

Config baselines and default reviews can enforce some privilege-related settings (one facet) but do not address code-level assignment/tracking logic that defines CWE-269.

PR.PS-05 partial match
prevents

PR.PS-05 can partially limit exploitability of some privilege issues via execution restrictions, but does not address the core design/implementation flaws of CWE-269 at all.

PR.DS-10 none match
prevents

PR.DS-10 protects data-in-use without touching privilege assignment/tracking, so it neither prevents CWE-269 nor removes more than one narrow facet of its risk.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.

prevents

The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.

prevents

Defining and communicating authorization levels for each role limits the assignment of excessive or unnecessary privileges.

mitigates

Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.

A.8.15 Logging partial match
finds

Logging every use of privileges and protecting those records makes it harder for an attacker who has obtained elevated rights to operate without leaving evidence.

mitigates

Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.
