OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in Telegram webhook authentication that allows attackers to brute-force weak webhook secrets. The vulnerability enables repeated authentication guesses without throttling, permitting attackers to systematically guess webhook secrets through brute-force attacks.

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability where silent local shared-auth reconnects auto-approve scope-upgrade requests, widening paired device permissions from operator.read to operator.admin. Attackers can exploit this by triggering local reconnection to silently escalate privileges and achieve remote code execution on the node.

OpenClaw before 2026.3.22 fails to enforce operator.admin scope on mutating internal ACP chat commands, allowing unauthorized modifications. Attackers without admin privileges can execute mutating control-plane actions by directly invoking affected ACP commands to bypass authorization gates.

OpenClaw through 2026.2.22 contains a symlink traversal vulnerability in agents.create and agents.update handlers that use fs.appendFile on IDENTITY.md without symlink containment checks. Attackers with workspace access can plant symlinks to append attacker-controlled content to arbitrary files, enabling remote code execution via crontab injection or unauthorized access via SSH key manipulation.

OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in Google Chat group policy enforcement that relies on mutable space display names. Attackers can rebind group policies by changing or colliding space display names to gain unauthorized access to protected resources.

OpenClaw before 2026.3.22 contains a policy confusion vulnerability in room authorization that matches colliding room names instead of stable room tokens. Attackers can exploit similarly named rooms to bypass allowlist policies and gain unauthorized access to protected Nextcloud Talk rooms.

OpenClaw before 2026.3.23 contains a replay identity vulnerability in Plivo V2 signature verification that allows attackers to bypass replay protection by modifying query parameters. The verification path derives replay keys from the full URL including query strings instead of the canonicalized base URL, enabling attackers to mint new verified request keys through unsigned query-only changes to signed requests.

OpenClaw before 2026.3.25 parses JSON request bodies before validating webhook signatures, allowing unauthenticated attackers to force resource-intensive parsing operations. Remote attackers can send malicious webhook requests to trigger denial of service by exhausting server resources through forced JSON parsing before signature rejection.

OpenClaw before 2026.3.22 contains a privilege escalation vulnerability in the device.pair.approve method that allows an operator.pairing approver to approve pending device requests with broader operator scopes than the approver actually holds. Attackers can exploit insufficient scope validation to escalate privileges to operator.admin and achieve remote code execution on the Node infrastructure.

OpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.
