Summary

CVE-2026-32267 is a high-severity Incorrect Authorization (CWE-863) vulnerability in Craftcms Craft Cms. Its CVSS base score is 7.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32267 is a privilege escalation vulnerability in Craft CMS, a content management system. It affects versions from 4.0.0-RC1 up to but not including 4.17.6, and from 5.0.0-RC1 up to but not including 5.9.12. The flaw resides in the UsersController->actionImpersonateWithToken function, which allows improper access control (CWE-863). The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity with network accessibility and no prerequisites for exploitation.

An attacker with low privileges, or even an unauthenticated user provided with a shared URL, can exploit this issue to escalate their access to administrator level. By abusing the impersonation token mechanism, the attacker gains full admin privileges, potentially enabling unauthorized data access, modification, or deletion across the CMS instance.

Craft CMS has addressed the vulnerability in versions 4.17.6 and 5.9.12, as detailed in the project's security advisory (GHSA-cc7p-2j3x-x7xf) and corresponding commit (6301e217c5f15617d939c432cb770db50af14b33). Security practitioners should prioritize upgrading affected installations to these patched releases to mitigate the risk.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

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

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
