Security Vulnerabilities
OpenClaw before 2026.3.31 contains a scope bypass vulnerability in webhook replay cache deduplication that allows authenticated attackers to replay messages across sibling targets using the same messageId. Attackers can exploit overly broad cache keying to bypass replay protection and deliver duplicate webhook messages to unintended targets.

OpenClaw before 2026.3.31 misclassifies proxied remote requests as loopback connections in the diffs viewer when allowRemoteViewer is disabled, allowing unauthorized access. Attackers can bypass access controls by sending proxied requests that are incorrectly identified as local loopback traffic, circumventing intended remote viewer restrictions.

OpenClaw before 2026.3.31 contains an incomplete scope-clearing vulnerability in trusted-proxy authentication mode that allows operator.admin privilege escalation. Attackers can exploit this by declaring operator scopes on non-Control-UI clients, allowing self-declared scopes to persist on identity-bearing authentication paths and escalate privileges.

OpenClaw before 2026.3.28 contains an exec allowlist bypass vulnerability where allow-always persistence fails to unwrap /usr/bin/script and similar wrappers before storing trust decisions. Attackers can obtain user approval for one wrapped command to persist trust for wrapper binaries that execute different underlying programs.

OpenClaw before 2026.3.31 fails to properly sanitize PIP_INDEX_URL and UV_INDEX_URL environment variables in host execution contexts, allowing attackers to redirect Python package-index traffic. Attackers can exploit this bypass to intercept or manipulate package management operations by injecting malicious index URLs through unsanitized environment variables.

OpenClaw before 2026.3.31 contains an exec allowlist bypass vulnerability allowing attackers to inherit allowlist trust via shell init-file wrapper invocations. Attackers can exploit shell options like --rcfile, --init-file, and --startup-file to load attacker-chosen initialization files while bypassing exec allowlist matching restrictions.

OpenClaw before 2026.3.28 contains a webhook replay vulnerability in Plivo V3 signature verification that canonicalizes query ordering for signatures but hashes raw URLs for replay detection. Attackers can reorder query parameters to bypass replay cache detection and trigger duplicate voice-call processing with a captured valid signed webhook.
