Summary

CVE-2026-63727 is a high-severity Incorrect Use of Privileged APIs (CWE-648) vulnerability in Anchore Enterprise (inferred from references). Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Abuse Elevation Control Mechanism (T1548); ranked at the 18th percentile by exploit likelihood (below the median); 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 SA-11 (Developer Testing and Evaluation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

Anchore Enterprise versions from 5.11.0 to 5.27.1 and 6.0.0 contain an improper privilege escalation vulnerability in the user management API. An authenticated attacker who is able to access the Anchore Enterprise API could issue an API call capable of modifying…

user permissions to gain access to additional resources and operations. It is not possible to grant the system-admin role, but a read only user could be granted write access. This issue is fixed in Anchore Enterprise 5.27.2 and 6.0.1.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incorrect calls to privileged APIs before deployment.

AC-3 Access Enforcement partial match

Enforces authorization checks around privileged operations so that an API requiring elevated rights cannot be reached or misused without proper rights.

AC-6 Least Privilege partial match

Least-privilege assignment directly reduces both the availability of privileged APIs and the blast radius when they are invoked incorrectly.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles include correct use of privileged interfaces and safe invocation patterns that stop the weakness from being introduced.

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.PS-06 mostly match
prevents

Secure SDLC practices directly enforce correct usage of privileged APIs during development.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect incorrect privileged API calls but does not prevent them at design time.

A.8.18 Use of privileged utility programs partial match
degrades

Restricting privileged utility programs limits the exposure of privileged APIs to misuse.

A.8.2 Privileged access rights partial match
degrades

Privileged access rights directly govern the correct use of privileged APIs and reduce misuse.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes API usage standards that can prevent incorrect privileged calls.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify correct invocation of privileged APIs.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles guide proper privilege separation and API usage.
