Summary

CVE-2026-41374 is a medium-severity Incorrect Behavior Order: Early Amplification (CWE-408) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 38th 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 SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw before 2026.3.31 performs Discord audio preflight transcription before validating member authorization, allowing unauthenticated attackers to consume resources. Remote attackers can trigger audio preflight processing without member allowlist validation to cause resource exhaustion.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Missing authorization check before resource-intensive audio transcription directly enables remote unauthenticated exploitation leading to application-level resource exhaustion (CWE-408).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires authorization validation before any privileged or resource-intensive operation such as audio preflight transcription.

prevent

Provides explicit denial-of-service protections against unauthenticated remote resource-exhaustion attacks that bypass authorization.

prevent

Enforces least-privilege restrictions so that even authenticated members cannot trigger expensive preflight processing without explicit need.

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-03 mostly match
prevents

Enforcing authentication before operations directly blocks the early expensive action described by the CWE.

PR.AA-05 mostly match
prevents

Policy-driven authorization enforcement prevents costly actions prior to proper access decisions.

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

Access control policies that enforce authentication before resource-intensive operations directly prevent early amplification.

degrades

Identity management ensures entities are identified and authenticated prior to performing expensive actions.

prevents

Access rights provisioning can restrict expensive operations until authorization is granted.

prevents

Privileged access rights limit who can perform costly actions but do not enforce authentication order.

prevents

Information access restriction mechanisms can block resource-intensive operations until authentication succeeds.

prevents

Secure authentication ensures identity verification occurs before expensive operations are allowed.
