Summary

CVE-2026-53824 is a medium-severity Insufficient Session Expiration (CWE-613) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.0 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application Access Token (T1550.001); ranked at the 8th 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-12 (Session Termination) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw before 2026.4.24 contains a token revocation vulnerability allowing callers with revoked slash tokens to continue executing commands during monitor refresh windows. Attackers can exploit stale token acceptance to invoke slash command behavior briefly after token revocation, potentially executing unauthorized…

T1550.001 Application Access Token Lateral Movement
Adversaries may use stolen application access tokens to bypass the typical authentication process and access restricted accounts, information, or services on remote systems.

T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Why these techniques?

Stale/revoked token acceptance directly enables use of application access tokens for unauthorized command execution via slash commands.

Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match
prevent

Directly requires prompt session/token termination so revoked slash tokens cannot be used after revocation.

AC-3 Access Enforcement good match
prevent

Enforces current access-control decisions, rejecting use of tokens whose revocation has already been recorded.

IA-5 Authenticator Management partial match
prevent

Requires timely revocation and update of authenticators (tokens), closing the refresh-window gap described in the CVE.

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.

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.
