Summary

CVE-2026-45005 is a medium-severity Operation on a Resource after Expiration or Release (CWE-672) vulnerability in Openclaw Openclaw. Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 21th 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 AC-3 (Access Enforcement) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Access enforcement applies current authorizations to every request, directly blocking operations once a resource has been revoked or released.

IA-5 Authenticator Management good match

Authenticator management mandates revocation and replacement procedures that render expired credentials unusable.

AC-2 Account Management partial match

Account lifecycle management includes explicit revocation and disabling steps that stop subsequent operations on released accounts or identifiers.

IA-4 Identifier Management partial match

Identifier management requires deallocation and reuse controls that prevent continued use of released identifiers.

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

Enforcing managed authorizations and revocations directly prevents post-release operations on credentials or entitlements.

PR.PS-06 mostly match
prevents

Secure development practices eliminate the root coding flaw that permits use-after-release.

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

Security testing can detect use-after-release but does not prevent it at runtime.

A.8.10 Information deletion partial match
degrades

Enforces timely deletion of resources so they cannot be used after release.

A.8.28 Secure coding partial match
prevents

Secure-coding rules require checks that prevent operations on freed or expired objects.

A.8.32 Change management partial match
prevents

Change-management processes can introduce or remove resource-lifetime controls.
