Security Impact
CVSS: 5.9
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N).
How to Fix CVE-2026-32039
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.
npm install openclaw@2026.2.22Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls openclawHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-32039, inspect your project dependencies using npm:
npm ls openclawAnalyze 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 2026.2.22), 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-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. 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.

"details" : "### Summary\n`channels.*.groups.*.toolsBySender` could match a privileged sender policy using a colliding mutable identity value (for example `senderName` or `senderUsername`) when deployments used untyped keys.\n\nThe fix introduces explicit typed sender keys (`id:`, `e164:`, `username:`, `name:`), keeps legacy untyped keys on a deprecated ID-only path, and adds regression coverage to prevent cross-identifier collisions.\n\n### Affected Packages / Versions\n- Package: npm `openclaw`\n- Affected versions: `<= 2026.2.21-2`\n- Latest published npm version at triage time (February 22, 2026): `2026.2.21-2`\n- Patched version (planned next release): `2026.2.22`\n\n### Impact\nThis is a sender-authorization bypass in group tool policy matching for deployments that use `toolsBySender` with untyped keys. Under those conditions, an attacker could inherit stronger tool permissions intended for another sender if they can force an identifier collision.\n\n### Fix Commit(s)\n- `5547a2275cb69413af3b62c795b93214fe913b57`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.22`). Once that npm release is published, this advisory should only need publishing.\n\nOpenClaw thanks @jiseoung for reporting.",
