AI-suggested

Since the vulnerability is due to insufficient allowlist enforcement and incorrect order of authorization checks, mitigation would involve applying the official fix once available or implementing strict authorization checks before processing transcription requests. Monitor vendor advisories for patch releases.

Description

OpenClaw versions before 2026.3.31 have a resource consumption vulnerability in the Telegram audio preflight transcription feature. Unauthorized group senders can trigger transcription processing without proper authorization checks due to insufficient allowlist enforcement. This can lead to resource or billing consumption by initiating audio preflight operations prematurely.
