Security Vulnerabilities
OpenClaw versions prior to 2026.2.26 fail to enforce sender authorization in member and message subtype system event handlers, allowing unauthorized events to be enqueued. Attackers can bypass Slack DM allowlists and per-channel user allowlists by sending system events from non-allowlisted senders through message_changed, message_deleted, and thread_broadcast events.

OpenClaw versions prior to 2026.2.21 BlueBubbles webhook handler contains a passwordless fallback authentication path that allows unauthenticated webhook events in certain reverse-proxy or local routing configurations. Attackers can bypass webhook authentication by exploiting the loopback/proxy heuristics to send unauthenticated webhook events to the BlueBubbles plugin.

OpenClaw versions prior to 2026.2.22 reuse gateway.auth.token as a fallback hash secret for owner-ID prompt obfuscation when commands.ownerDisplay is set to hash and commands.ownerDisplaySecret is unset, creating dual-use of authentication secrets across security domains. Attackers with access to system prompts sent to third-party model providers can derive the gateway authentication token from the hash outputs, compromising gateway authentication security.

OpenClaw versions prior to 2026.2.23 contain an authorization bypass vulnerability in the ACP client that auto-approves tool calls based on untrusted toolCall.kind metadata and permissive name heuristics. Attackers can bypass interactive approval prompts for read-class operations by spoofing tool metadata or using non-core read-like names to reach auto-approve paths.

OpenClaw versions prior to 2026.2.22 fail to sanitize shell startup environment variables HOME and ZDOTDIR in the system.run function, allowing attackers to bypass command allowlist protections. Remote attackers can inject malicious startup files such as .bash_profile or .zshenv to achieve arbitrary code execution before allowlist-evaluated commands are executed.

OpenClaw versions prior to 2026.2.25 contain an authentication bypass vulnerability in the trusted-proxy Control UI pairing mechanism that accepts client.id=control-ui without proper device identity verification. An authenticated node role websocket client can exploit this by using the control-ui client identifier to skip pairing requirements and gain unauthorized access to node event execution flows.

OpenClaw versions prior to 2026.2.26 contain an approval context-binding weakness in system.run execution flows with host=node that allows reuse of previously approved requests with modified environment variables. Attackers with access to an approval id can exploit this by reusing an approval with changed env input, bypassing execution-integrity controls in approval-enabled workflows.

OpenClaw versions prior to 2026.2.21 sandbox browser entrypoint launches x11vnc without authentication for noVNC observer sessions, allowing unauthenticated access to the VNC interface. Remote attackers on the host loopback interface can connect to the exposed noVNC port to observe or interact with the sandbox browser without credentials.

OpenClaw versions prior to 2026.2.25 contain an approval-integrity bypass vulnerability in system.run where rendered command text is used as approval identity while trimming argv token whitespace, but runtime execution uses raw argv. An attacker can craft a trailing-space executable token to execute a different binary than what the approver displayed, allowing unexpected command execution under the OpenClaw runtime user when they can influence command argv and reuse an approval context.

OpenClaw versions prior to 2026.3.1 contain an authorization mismatch vulnerability that allows authenticated callers with operator.write scope to invoke owner-only tool surfaces including gateway and cron through agent runs in scoped-token deployments. Attackers with write-scope access can perform control-plane actions beyond their intended authorization level by exploiting inconsistent owner-only gating during agent execution.
