Summary

CVE-2026-41382 is a low-severity Missing Authorization (CWE-862) vulnerability in Openclaw Openclaw. Its CVSS base score is 2.3 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 13th 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 before 2026.3.31 contains an authorization bypass vulnerability in Discord voice ingress that allows attackers to bypass channel and member allowlist restrictions. Attackers can exploit stale-role validation gaps and improper channel name validation to gain unauthorized access to restricted voice…

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-862) in public-facing Discord voice ingress directly enables exploitation of the exposed application for unauthorized access.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization policy on channel/member allowlists, blocking the bypass of stale-role and name validation checks.

prevent

Limits privileges to only explicitly authorized voice-channel roles, reducing the impact of any validation-gap bypass.

prevent

Enforces information-flow rules between Discord voice channels and users, preventing unauthorized ingress despite flawed allowlist checks.

PR.AA-05 full match
prevents

Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing 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 authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.

prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

detects

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

prevents

Defining authorization responsibilities and reviewing risk-treatment progress throughout the project lifecycle catches missing authorization checks before the system is deployed.
