Vulnerability Data

OpenClaw before 2026.4.22 contains a webhook secret revocation bypass vulnerability allowing callers with old Slack and Zalo webhook secrets to remain active after secrets.reload. Attackers can exploit the stale-secret window to deliver webhook events after operator-expected secret revocation, potentially accepting…

Mitigating Controls (NIST 800-53 r5) AI

IA-5 Authenticator Management good match
prevent

Directly requires revocation and replacement of authenticators (webhook secrets) so that previously issued values are no longer accepted after reload.

AC-12 Session Termination good match
prevent

Mandates timely termination of sessions or tokens using stale credentials, closing the window in which old Slack/Zalo secrets remain valid.

AC-3 Access Enforcement partial match
prevent

Enforces access decisions using only currently authorized secrets, rejecting any webhook event presented with a revoked credential.

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-01 mostly match
prevents

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-05 mostly match
prevents

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.

PR.AA-03 partial match
prevents

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

A.8.5 Secure authentication none match
none

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
