OpenClaw Slack: dmPolicy=open allowed any DM sender to run privileged slash commands

Moderate severity GitHub Reviewed Published Feb 15, 2026 in openclaw/openclaw • Updated Feb 18, 2026

Package

npm openclaw (npm)

Affected versions

< 2026.2.14

Patched versions

2026.2.14

Description

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 (aka dmPolicy=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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
