CVE-2026-32980: OpenClaw Telegram webhook request bodies were read before secret validation, enabling unauthenticated resource exhaustion
(updated )
openclaw versions <= 2026.3.12 read and buffered Telegram webhook request bodies before validating x-telegram-bot-api-secret-token. This let unauthenticated callers force up to the configured webhook body limit of pre-auth body I/O and JSON parse work per request.
