Summary

CVE-2026-32027 is a high-severity Incorrect Authorization (CWE-863) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15th 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 AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw versions prior to 2026.2.26 contain an authorization bypass vulnerability where DM pairing-store identities are incorrectly eligible for group allowlist authorization checks. Attackers can exploit this cross-context authorization flaw by using a sender approved via DM pairing to satisfy group…

sender allowlist checks without explicit presence in groupAllowFrom, bypassing group message access controls.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Authorization bypass (CWE-863) in group access controls directly enables remote exploitation of the application to obtain unauthorized message access.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions so that only identities explicitly present in groupAllowFrom can send group messages, blocking the DM-pairing cross-context bypass.

prevent

Enforces information-flow rules that separate DM-pairing identity contexts from group allowlist checks, preventing unauthorized sender eligibility across boundaries.

prevent

Requires correct, context-aware access-control decisions rather than incorrectly treating DM-paired identities as valid for groupAllowFrom checks.

PR.AA-05 mostly match
prevents

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.
