GHSA-c447-w54g-f55j

Duplicate Advisory: OpenClaw Telegram webhook request bodies were read before secret validation, enabling unauthenticated resource exhaustion

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-jq3f-vjww-8rq7. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.3.13 reads and buffers Telegram webhook request bodies before validating the x-telegram-bot-api-secret-token header, allowing unauthenticated attackers to exhaust server resources. Attackers can send POST requests to the webhook endpoint to force memory consumption, socket time, and JSON parsing work before authentication validation occurs.
