DescriptionNVD

OpenClaw before 2026.3.31 contains a resource consumption vulnerability in Telegram audio preflight transcription that allows unauthorized group senders to trigger transcription processing. Attackers can exploit insufficient allowlist enforcement to cause resource or billing consumption by initiating audio preflight operations before authorization checks are applied.

AnalysisAI

OpenClaw before version 2026.3.31 allows unauthenticated remote attackers to trigger resource-intensive audio transcription processing via Telegram without proper authorization, enabling denial-of-service through billing or infrastructure exhaustion. The vulnerability stems from insufficient allowlist enforcement that permits unauthorized group senders to initiate preflight transcription operations before authentication is validated, and no public exploit code has been identified at the time of analysis.
