Summary

CVE-2026-59133 is a high-severity Execution with Unnecessary Privileges (CWE-250) vulnerability in Microsoft Windows App. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 43% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match

Least privilege directly requires that only the minimum necessary authorizations are granted, structurally eliminating execution with unnecessary privileges.

Mitigating Controls (NIST CSF 2.0) AI

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 directly enforces least privilege so largely eliminates CWE-250 at design time, yet the weakness can still arise from runtime escalation paths, third-party code, or misapplied role definitions outside this single control.

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.

A.5.18 Access rights mostly match
prevents

Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.

A.8.18 Use of privileged utility programs mostly match
prevents

Restricting privileged utilities to the fewest trusted users and requiring explicit authorization directly stops developers or operators from embedding or invoking code that runs with unnecessary elevated rights.

A.8.2 Privileged access rights mostly match
prevents

Mandating separate non-privileged identities for routine work and restricting privileged accounts to administrative tasks reduces the chance that everyday operations run with unnecessary elevated rights.

A.8.9 Configuration management mostly match
prevents

The control explicitly calls for minimizing privileged identities and disabling unnecessary accounts, thereby reducing the number of processes that run with unnecessary privileges.

A.5.15 Access control partial match
prevents

The requirement to restrict privileged access and apply segregation of duties limits the number of processes or accounts that must run with elevated rights, lowering the impact of unnecessary privilege assignments.

A.5.3 Segregation of duties partial match
mitigates

Forcing distinct roles for initiating versus executing changes reduces the chance that an individual will run with unnecessary privileges to perform both steps.
