Summary
OpenClaw Slack: dmPolicy=open allowed any DM sender to run privileged slash commands
Details
Summary
When Slack DMs are configured with dmPolicy=open, the Slack slash-command handler incorrectly treated any DM sender as command-authorized. This allowed any Slack user who could DM the bot to execute privileged slash commands via DM, bypassing intended allowlist/access-group restrictions.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.13 - Affected configuration: Slack DMs enabled with
channels.slack.dm.policy: open(akadmPolicy=open)
Impact
Any Slack user in the workspace who can DM the bot could invoke privileged slash commands via DM.
Fix
The slash-command path now computes CommandAuthorized for DMs using the same allowlist/access-group gating logic as other inbound paths.
Fix commit(s): - f19eabee54c49e9a2e264b4965edf28a2f92e657
Release Process Note
patched_versions is set to the planned next release (2026.2.14). Once that npm release is published, this advisory should be published.
Thanks @christos-eth for reporting.
