- CLI: avoid loading provider discovery during startup model normalization. (#46522) Thanks @ItsAditya-xyz and @vincentkoc.
- Agents/Telegram: avoid rebuilding the full model catalog on ordinary inbound replies so Telegram message handling no longer pays multi-second core startup latency before reply generation. Thanks @vincentkoc.
- Gateway/Discord startup: load only configured channel plugins during gateway boot, and lazy-load Discord provider/session runtime setup so startup stops importing unrelated providers and trims cold-start delay. Thanks @vincentkoc.
- Security/exec: harden macOS allowlist resolution against wrapper and `env` spoofing, require fresh approval for inline interpreter eval with `tools.exec.strictInlineEval`, wrap Discord guild message bodies as untrusted external content, and add audit findings for risky exec approval and open-channel combinations.
- Agents/inbound: lazy-load media and link understanding for plain-text turns and cache synced auth stores by auth-file state so ordinary inbound replies avoid unnecessary startup churn. Thanks @vincentkoc.
- Telegram/polling: hard-timeout stuck `getUpdates` requests so wedged network paths fail over sooner instead of waiting for the polling stall watchdog. Thanks @vincentkoc.
- Agents/models: cache `models.json` readiness by config and auth-file state so embedded runner turns stop paying repeated model-catalog startup work before replies. Thanks @vincentkoc.

- Run sensitive tool execution in a sandbox; keep secrets out of the agent’s reachable filesystem.
- Note: sandboxing is opt-in. If sandbox mode is off, exec runs on the gateway host even though tools.exec.host defaults to sandbox, and host exec does not require approvals unless you set host=gateway and configure exec approvals.
- Limit high-risk tools (`exec`, `browser`, `web_fetch`, `web_search`) to trusted agents or explicit allowlists.
- If you allowlist interpreters (`python`, `node`, `ruby`, `perl`, `php`, `lua`, `osascript`), enable `tools.exec.strictInlineEval` so inline eval forms still need explicit approval.
- **Model choice matters:** older/smaller/legacy models are significantly less robust against prompt injection and tool misuse. For tool-enabled agents, use the strongest latest-generation, instruction-hardened model available.

### Inline interpreter eval hardening (`tools.exec.strictInlineEval`)
When `tools.exec.strictInlineEval=true`, OpenClaw treats inline code-eval forms as approval-only even if the interpreter binary itself is allowlisted.
Examples:
- `python -c`
- `node -e`, `node --eval`, `node -p`
- `ruby -e`
- `perl -e`, `perl -E`
- `php -r`
- `lua -e`
- `osascript -e`
This is defense-in-depth for interpreter loaders that do not map cleanly to one stable file operand. In strict mode:
- these commands still need explicit approval;
- `allow-always` does not persist new allowlist entries for them automatically.

etc.) so inner executables are persisted instead of multiplexer binaries. If a wrapper or
multiplexer cannot be safely unwrapped, no allowlist entry is persisted automatically.
If you allowlist interpreters like `python3` or `node`, prefer `tools.exec.strictInlineEval=true` so inline eval still requires an explicit approval.

- `tools.exec.safeBinTrustedDirs`: additional explicit directories trusted for `safeBins` path checks. `PATH` entries are never auto-trusted. Built-in defaults are `/bin` and `/usr/bin`.
@ -143,6 +144,7 @@ Use the two controls for different jobs:
Do not treat `safeBins` as a generic allowlist, and do not add interpreter/runtime binaries (for example `python3`, `node`, `ruby`, `bash`). If you need those, use explicit allowlist entries and keep approval prompts enabled.
`openclaw security audit` warns when interpreter/runtime `safeBins` entries are missing explicit profiles, and `openclaw doctor --fix` can scaffold missing custom `safeBinProfiles` entries.
If you explicitly allowlist interpreters, enable `tools.exec.strictInlineEval` so inline code-eval forms still require a fresh approval.
For full policy details and examples, see [Exec approvals](/tools/exec-approvals#safe-bins-stdin-only) and [Safe bins versus allowlist](/tools/exec-approvals#safe-bins-versus-allowlist).
