How to Fix CVE-2026-32918

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: 2026.3.11 
npm install openclaw@2026.3.11
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-2026-32918, 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 2026.3.11), 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. 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 The built-in `session_status` tool did not enforce the intended session-visibility boundary. A sandboxed subagent could supply another session's `sessionKey` and inspect or modify state outside its own sandbox scope. ### Impact This allowed a sandboxed child session to read parent or sibling session data and, in affected releases, update the target session's persisted model override. ### Affected versions `openclaw` `<= 2026.3.8` ### Patch Fixed in `openclaw` `2026.3.11` and included in later releases such as `2026.3.12`. Session visibility checks now enforce the sandbox boundary before reading or mutating session state.
