OpenClaw: Telegram audio preflight transcription enables resource consumption by unauthorized senders
Summary
Telegram audio preflight transcription enables resource consumption by unauthorized senders
Current Maintainer Triage
- Status: narrow
- Normalized severity: medium
- Assessment: v2026.3.28 still lets unauthorized Telegram group senders trigger audio preflight before allowlist enforcement, but the real impact is resource or billing burn rather than direct data exposure or host compromise.
