Vulnerability Data

OpenClaw before 2026.3.31 contains a session visibility bypass vulnerability where the session_status function fails to enforce configured tools.sessions.visibility restrictions for unsandboxed invocations. Attackers can invoke session_status without sandbox constraints to bypass session-policy controls and access restricted session information.

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

Bypass of session visibility controls directly enables unauthorized retrieval of restricted local session data.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces the tools.sessions.visibility restrictions that the session_status function fails to apply for unsandboxed calls.

prevent

Limits privileges so that even unsandboxed invocations cannot reach restricted session information without explicit need-to-know authorization.

prevent

Enforces information-flow rules on session data, blocking the unauthorized disclosure that occurs when visibility policies are bypassed.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

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.

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.
