CVE-2026-28454
OpenClaw has a potential access-group authorization bypass if channel type lookup fails
Severity by source
Trivy's own label is CRITICAL. Rated critical by NVD, GHSA.
Description
OpenClaw versions prior to 2026.2.2 fail to validate webhook secrets in Telegram webhook mode (must be enabled), allowing unauthenticated HTTP POST requests to the webhook endpoint that trust attacker-controlled JSON payloads. Remote attackers can forge Telegram updates by spoofing message.from.id and chat.id fields to bypass sender allowlists and execute privileged bot commands.
