OpenClaw before 2026.3.28 contains an execution approval vulnerability in exec-approvals-allowlist.ts that allows allow-always persistence to trust wrapper carrier executables instead of invoked targets. Attackers can exploit positional carrier executable routing through dispatch wrappers to establish broader allowlist entries than intended, weakening execution approval boundaries.

OpenClaw before 2026.3.31 contains an incomplete host-env-security-policy.json that fails to restrict compiler binary environment variables, allowing untrusted models to substitute CC, CXX, CARGO_BUILD_RUSTC, and CMAKE_C_COMPILER via environment overrides. Attackers with approved host-exec requests can override compiler binaries to execute arbitrary code during build processes.

OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in chat.send that allows write-scoped gateway callers to trigger admin-only session reset operations. Attackers can rotate target sessions, archive prior transcript state, and force new session IDs without requiring admin scope by exploiting improper authorization checks in the chat.send path.

OpenClaw before 2026.4.2 fails to normalize trailing-dot localhost hosts in remote CDP discovery responses, allowing bypass of loopback protections. Attackers can craft hostile discovery responses returning localhost. to retarget authenticated browser control toward localhost endpoints and expose browser state.

OpenClaw versions 2026.2.19 before 2026.3.31 contain an improper cache isolation vulnerability in the Zalo webhook replay-dedupe mechanism that is shared across authenticated webhook targets. Attackers controlling one authenticated Zalo webhook path in multi-account deployments can suppress legitimate events on different accounts by matching event_name and message_id parameters.

OpenClaw versions 2026.2.6 through 2026.3.24 contain a path traversal vulnerability in the Feishu extension resolveUploadInput function that bypasses file-system sandbox restrictions. Attackers can exploit improper path resolution during upload_image operations to read arbitrary files outside configured localRoots boundaries.
