Security Vulnerabilities
OpenClaw versions prior to 2026.2.13 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually recover the authentication token.

OpenClaw versions 2026.1.29-beta.1 prior to 2026.2.14 contain a vulnerability in the sandbox browser bridge server in which it accepts requests without requiring gateway authentication, allowing local attackers to access browser control endpoints. A local attacker can enumerate tabs, retrieve WebSocket URLs, execute JavaScript, and exfiltrate cookies and session data from authenticated browser contexts.

OpenClaw versions prior to 2026.2.14 contain a webhook routing vulnerability in the Google Chat monitor component that allows cross-account policy context misrouting when multiple webhook targets share the same HTTP path. Attackers can exploit first-match request verification semantics to process inbound webhook events under incorrect account contexts, bypassing intended allowlists and session policies.

OpenClaw versions prior to 2026.2.2 contain an exec approvals (must be enabled) allowlist bypass vulnerability that allows attackers to execute arbitrary commands by injecting command substitution syntax. Attackers can bypass the allowlist protection by embedding unescaped $() or backticks inside double-quoted strings to execute unauthorized commands.

OpenClaw version 2026.1.14-1 prior to 2026.2.2, with the Matrix plugin installed and enabled, contain a vulnerability in which DM allowlist matching could be bypassed by exact-matching against sender display names and localparts without homeserver validation. Remote Matrix users can impersonate allowed identities by using attacker-controlled display names or matching localparts from different homeservers to reach the routing and agent pipeline.

OpenClaw exec-approvals allowlist validation checks pre-expansion argv tokens but execution uses real shell expansion, allowing safe bins like head, tail, or grep to read arbitrary local files via glob patterns or environment variables. Authorized callers or prompt-injection attacks can exploit this to disclose files readable by the gateway or node process when host execution is enabled in allowlist mode.

OpenClaw versions prior to 2026.2.12 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually determine the authentication token.

OpenClaw's voice-call plugin versions before 2026.2.3 contain an improper authentication vulnerability in webhook verification that allows remote attackers to bypass verification by supplying untrusted forwarded headers. Attackers can spoof webhook events by manipulating Forwarded or X-Forwarded-* headers in reverse-proxy configurations that implicitly trust these headers.

OpenClaw versions prior to 2026.2.14 contain a vulnerability in the gateway in which it fails to sanitize internal approval fields in node.invoke parameters, allowing authenticated clients to bypass exec approval gating for system.run commands. Attackers with valid gateway credentials can inject approval control fields to execute arbitrary commands on connected node hosts, potentially compromising developer workstations and CI runners.

OpenClaw versions prior to 2026.2.2 contain a server-side request forgery vulnerability in attachment and media URL hydration that allows remote attackers to fetch arbitrary HTTP(S) URLs. Attackers who can influence media URLs through model-controlled sendAttachment or auto-reply mechanisms can trigger SSRF to internal resources and exfiltrate fetched response bytes as outbound attachments.
