CVE-2026-41359Network attack vector

Authenticated privilege escalation via ungated send writeback

Published Apr 23, 2026 · Updated Apr 23, 2026

Privilege escalation in OpenClaw before 2026.3.28 allows remote authenticated users to alter protected Telegram and cron settings. The Gateway send method passed operator.write requests into legacy Telegram target writeback without requiring operator.admin, allowing protected configuration to be persisted. Valid operator.write credentials and a reachable Gateway are required; the resulting writes can alter Telegram routing and cron-backed persistence.
