 - Security/Logging: redact Telegram bot tokens from error messages and uncaught stack traces to prevent accidental secret leakage into logs. Thanks @aether-ai-agent.
 - Sandbox/Security: block dangerous sandbox Docker config (bind mounts, host networking, unconfined seccomp/apparmor) to prevent container escape via config injection. Thanks @aether-ai-agent.
+- LINE/Security: fail closed on webhook startup when channel token or channel secret is missing, and treat LINE accounts as configured only when both are present. (#17587) Thanks @davidahmann.
 - Agents/Sandbox: clarify system prompt path guidance so sandbox `bash/exec` uses container paths (for example `/workspace`) while file tools keep host-bridge mapping, avoiding first-attempt path misses from host-only absolute paths in sandbox command execution. (#17693) Thanks @app/juniordevbot.
 - Control UI: prevent stored XSS via assistant name/avatar by removing inline script injection, serving bootstrap config as JSON, and enforcing `script-src 'self'`. Thanks @Adam55A-code.
 - Gateway/Control UI: preserve requested operator scopes for Control UI bypass modes (`allowInsecureAuth` / `dangerouslyDisableDeviceAuth`) when device identity is unavailable, preventing false `missing scope` failures on authenticated LAN/HTTP operator sessions. (#17682) Thanks @leafbird.
