CVE-2026-27004: OpenClaw session tool visibility hardening and Telegram webhook secret fallback

February 18, 2026 (updated February 20, 2026)

Shared-agent, multi-user, less-trusted environments: session-tool access could expose transcript content across peer sessions.
Single-agent or trusted environments: practical impact is limited.
Telegram webhook mode: account-level secret wiring could be missed unless an explicit monitor webhook secret override was provided.
