Security Vulnerabilities
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 2026.3.25 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 an information disclosure vulnerability that allows attackers with operator.read scope to expose credentials embedded in channel baseUrl and httpUrl fields. Attackers can access gateway snapshots via config.get and channels.status endpoints to retrieve sensitive authentication information from URL userinfo components.

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 2026.3.22 contains an unbounded memory allocation vulnerability in remote media HTTP error handling that allows attackers to trigger excessive memory consumption. Attackers can send crafted HTTP error responses with large bodies to remote media endpoints, causing the application to allocate unbounded memory before failure handling occurs.

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.

OpenClaw before 2026.3.22 contains a webhook path route replacement vulnerability in the Synology Chat extension that allows attackers to collapse multi-account configurations onto shared webhook paths. Attackers can exploit inherited or duplicate webhook paths to bypass per-account DM access control policies and replace route ownership across accounts.

OpenClaw versions 2026.3.11 through 2026.3.24 contain a session isolation bypass vulnerability where session_status resolves sessionId to canonical session keys before enforcing visibility checks. Sandboxed child sessions can exploit this to access parent or sibling sessions that should be blocked by explicit sessionKey restrictions.

OpenClaw before 2026.3.22 performs cite expansion before completing channel and DM authorization checks, allowing cite work and content handling prior to final auth decisions. Attackers can exploit this timing vulnerability to access or manipulate content before proper authorization validation occurs.
