How to Fix CVE-2026-26328

To remediate this vulnerability, upgrade all affected Openclaw 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
clawdbot fixed: 2026.2.14 
npm install clawdbot@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-2026-26328, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Openclaw 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Openclaw, 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 Under iMessage `groupPolicy=allowlist`, group authorization could be satisfied by sender identities coming from the DM pairing store, broadening DM trust into group contexts. ## Details Affected component: `src/imessage/monitor/monitor-provider.ts`. Vulnerable logic derived `effectiveGroupAllowFrom` using both the static group allowlist and DM pairing-store identities (`storeAllowFrom`). This allowed a sender approved via DM pairing to satisfy group authorization in groups even if the sender/chat was not explicitly present in `groupAllowFrom`. This weakens boundary separation between DM pairing and group allowlist authorization. ## Affected Packages / Versions - `openclaw` (npm): affected `<= 2026.2.13` - `clawdbot` (npm): affected `<= 2026.1.24-3` ## Fix Commit(s) - `openclaw/openclaw@872079d42fe105ece2900a1dd6ab321b92da2d59` - `openclaw/openclaw@90d1e9cd71419168b2faa54a759b124a3eacfae7` Thanks @vincentkoc for reporting.
