How to Fix CVE-2026-32036

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: 2026.2.26
npm install openclaw@2026.2.26
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-2026-32036, 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 2026.2.26), 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-289: Authentication Bypass by Alternate Name, where the product performs authentication based on the name of a resource being accessed, or the name of the actor performing the access, but it does not properly check all possible names for that resource or 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 Gateway plugin route auth protection for `/api/channels` could be bypassed using encoded dot-segment traversal (for example `..%2f`) in path variants that plugin handlers normalize. ### Affected Packages / Versions - Package: npm `openclaw` - Latest published vulnerable version: `2026.2.25` - Vulnerable version range: `<= 2026.2.25` - Patched version: `2026.2.26` (planned next release) ### Impact Under affected versions, crafted alternate paths could bypass gateway auth checks for protected plugin channel routes when plugin handlers decode/canonicalize the incoming path and then route to `/api/channels/...` handlers. ### Fix Commit(s) - `258d615c45527ffda37cecd08cd268f97461bde0` ### Release Process Note `patched_versions` is pre-set to the planned next release (`2026.2.26`). After npm publish, maintainers only need to publish the advisory. OpenClaw thanks @zpbrent for reporting.
