OpenClaw before 2026.3.31 lacks a shared pre-auth concurrency budget on the public LINE webhook path, allowing attackers to cause transient availability loss. Remote attackers can flood the webhook endpoint with concurrent requests before signature verification to exhaust resources and degrade service availability.

OpenClaw before 2026.3.31 contains a replay detection bypass vulnerability in webhook signature handling that treats Base64 and Base64URL encoded signatures as distinct requests. Attackers can re-encode Telnyx webhook signatures to bypass replay detection while maintaining valid signature verification.

OpenClaw before 2026.4.2 contains an approval integrity vulnerability in pnpm dlx that fails to bind local script operands consistently with pnpm exec flows. Attackers can replace approved local scripts before execution without invalidating the approval plan, allowing execution of modified script contents.

OpenClaw before 2026.4.20 contains an improper authorization vulnerability in paired-device pairing management that allows limited-scope sessions to enumerate and act on pairing requests. Attackers with paired-device access can approve or operate on unrelated pending device requests within the same gateway scope.

OpenClaw before 2026.3.31 contains a credential exposure vulnerability in media download functionality that forwards Authorization headers across cross-origin redirects. Attackers can exploit this by crafting malicious cross-origin redirect chains to intercept sensitive authorization credentials intended for legitimate requests.

OpenClaw before 2026.3.31 contains a remote code execution vulnerability where a device-paired node can bypass the node scope gate authentication mechanism. Attackers with device pairing credentials can execute arbitrary node commands on the host system without proper node pairing validation.

OpenClaw before 2026.3.31 contains an environment variable override vulnerability in host exec policy that fails to properly enforce proxy, TLS, Docker, and Git TLS controls. Attackers can bypass security controls by overriding environment variables to circumvent proxy settings, TLS verification, Docker restrictions, and Git TLS enforcement.

OpenClaw before 2026.4.2 accepts non-loopback cleartext ws:// gateway endpoints and transmits stored gateway credentials over unencrypted connections. Attackers can forge discovery results or craft setup codes to redirect clients to malicious endpoints, disclosing plaintext gateway credentials.

OpenClaw before 2026.3.31 contains a server-side request forgery vulnerability in the marketplace plugin download functionality that allows attackers to access internal resources by following unvalidated redirects. The marketplace.ts module fails to restrict redirect destinations during archive downloads, enabling remote attackers to redirect requests to arbitrary internal or external servers.

OpenClaw before 2026.3.31 contains a time-of-check-time-of-use race condition in the remote filesystem bridge readFile function that allows sandbox escape. Attackers can exploit the separate path validation and file read operations to bypass sandbox restrictions and read arbitrary files.
