CVE-2026-28392Network attack vector

Privilege escalation via default-allow DM command authorization

Published Mar 5, 2026 · Updated Mar 5, 2026

Incorrect authorization in OpenClaw before 2026.2.14 allows remote attackers to run privileged Slack slash commands through bot DMs. The Slack slash-command handler initialized CommandAuthorized as true and retained it for direct messages under dmPolicy=open instead of applying allowlist and access-group authorizers. Exploitation requires Slack DMs and dmPolicy=open; any workspace user able to message the bot can bypass restrictions and invoke its privileged command set.
