How to Fix CVE-2026-33572

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: 2026.2.17 
npm install openclaw@2026.2.17
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-2026-33572, 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 2026.2.17), 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-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. 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

`openclaw` created new session transcript JSONL files with overly broad default permissions in affected releases. On multi-user hosts, other local users or processes could read transcript contents, including secrets that might appear in tool output. ## Affected Packages / Versions - Package: `openclaw` (`npm`) - Affected versions: `<= 2026.2.15` - First fixed version: `2026.2.17` - Current latest npm release checked during verification: `2026.3.13` (not affected) ## Impact Session transcript JSONL files are created under the local OpenClaw session store. In affected releases, newly created transcript files did not force user-only permissions, so transcript contents could be readable by other local users depending on the host environment and umask behavior. ## Fix New transcript files are now created with `0o600` permissions. Existing transcript permission drift is also remediated by the security audit fix flow. Verified in code: - `src/config/sessions/transcript.ts:82` writes new transcript files with `mode: 0o600` - `src/config/sessions/sessions.test.ts:303` includes regression coverage asserting `0o600` ## Fix Commit(s) - `095d522099653367e1b76fa5bb09d4ddf7c8a57c` ## Release Note This fix first shipped in `2026.2.17` and is present in the current npm release `2026.3.13`.
