What is the OpenClaw reasoning leak bug?

OpenClaw's internal reasoning and thinking blocks leak into user-visible chat messages across Discord, Telegram, WhatsApp, and Web UI, exposing the agent's internal planning to end users.

Which OpenClaw versions are affected by reasoning leaks?

The bug has been documented from v2026.2.22 through v2026.4.9 and later, recurring across multiple versions as a regression.

Is the OpenClaw reasoning leak a security risk?

Yes — leaked reasoning text can expose system prompts, tool arguments, URLs, credentials, and internal planning, making it a compounding privacy breach and potential social engineering vector.

How many GitHub issues document the OpenClaw reasoning leak?

At least 9 separate GitHub issues document reasoning content leaking across Discord, Telegram, WhatsApp, and Web UI.

Can the OpenClaw reasoning leak be disabled?

Disabling thinking in agent config helps but issue #40736 documents leaks even when thinking is explicitly disabled, suggesting a deeper message formatting boundary failure.

OpenClaw Internal Reasoning Leaks Into User-Visible Messages Across Discord, Telegram, WhatsApp, and Web UI

OpenClaw's internal reasoning and thinking blocks leak into user-visible chat responses across all major channel platforms. At least 9 GitHub issues document the recurring bug spanning Discord, Telegram, WhatsApp, and Web UI. Penligent.ai security analysis frames it as compounding privacy breach where internal planning text gets persisted to session history. Affects multiple models and versions from v2026.2.22 through v2026.4.9+.

Product Idea from this Signal

A runtime middleware that intercepts OpenClaw agent failures, reasoning leaks, memory timeouts, and processing stalls before they reach end users

446 ▲

OpenClaw agents fail in at least four distinct patterns that existing monitoring tools only detect after the damage is done. Internal reasoning text leaks into user-visible messages across Discord, Telegram, and WhatsApp (9+ open GitHub issues, recurring across versions). Active Memory timeouts kill all conversations after upgrades. Processing lanes stall for minutes with no automatic recovery. Codex runtime injects 30K tokens of overhead per turn making interactive use impossible. This middleware sits between the OpenClaw Gateway and channel outputs, pattern-matches known failure signatures in real time, and either suppresses the bad output (reasoning leaks), force-resets stuck lanes (stalls), or falls back to a cached last-good response (timeouts) before the user ever sees the error.
