CVE-2026-45001
📛 CVE Title
OpenClaw < 2026.4.20 - Gateway Config Mutation Guard Bypass via Agent Tool Access
Description
OpenClaw before 2026.4.20 contains a guard bypass vulnerability in the agent-facing gateway config.patch and config.apply endpoints that fails to protect operator-trusted settings including sandbox policy, plugin enablement, gateway auth/TLS, hook routing, MCP server configuration, SSRF policy, and filesystem hardening. A prompt-injected model with access to the owner-only gateway tool can persist unauthorized changes to protected operator settings.
