CVE-2026-45216
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-45216 is a high-severity Incorrect Privilege Assignment (CWE-266) vulnerability. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 35th 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-6 (Least Privilege) and AC-2 (Account Management) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.
Account management defines and authorizes the exact privileges granted to each account or role.
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.

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.
Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.

A.5.15 directly requires determining access needs, defining/enforcing topic-specific access control policy and rules (including need-to-know, privilege restrictions, segregation, formal authorization, role-based mapping, and consistency with classification), which stops most incorrect privilege assignments from being exploitable; the bounded remainder is incorrect assignments that arise from flawed implementation of those rules rather than from their absence.
A.5.18's provisioning, review, revocation and SoD rules (esp. a,b,c,f,i,j) directly stop most incorrect privilege assignments from being granted or persisting, with a bounded remainder in flawed implementation of the authorization step itself (see 5.9/5.15 dependency)
A.8.2 directly controls the identification, allocation, review, expiry, and temporary nature of privileged rights per policy, which stops most incorrect assignments from creating an exploitable sphere of control; the bounded remainder is incorrect privilege semantics inside code that the authorization process never sees.
Information-access-restriction mechanisms enforce the correct privilege boundaries once assignment rules are defined.
