How to Fix CVE-2026-28392

To remediate this vulnerability, upgrade all affected OpenClaw Slack dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.2.14 
npm install openclaw@2026.2.14
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-28392, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of OpenClaw Slack in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.14), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In OpenClaw Slack, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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.
