How to Fix CVE-2026-35658

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: 2026.3.2 
npm install openclaw@2026.3.2
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-2026-35658, 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 2026.3.2), 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. 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 `image` tool did not fully honor the `tools.fs.workspaceOnly` filesystem boundary. In affected releases, image-path resolution could still traverse sandbox bridge mounts outside the workspace and read files from mounted directories that the other file tools would reject. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `< 2026.3.2` - Fixed: `>= 2026.3.2` - Latest released tags checked: `v2026.3.23` (`ccfeecb6887cd97937e33a71877ad512741e82b2`) and `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `dd9d9c1c609dcb4579f9e57bd7b5c879d0146b53` - `14baadda2c456f3cf749f1f97e8678746a34a7f4` ## Release Status The complete fix shipped in `v2026.3.2` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - `src/agents/openclaw-tools.ts` now passes `fsPolicy` into `createImageTool`, so the image tool receives the same workspace-only policy input as the other filesystem tools. - `src/agents/tools/image-tool.ts`, `src/agents/tools/media-tool-shared.ts`, and `src/agents/sandbox-media-paths.ts` now restrict local roots and sandbox-bridge resolution to the workspace when `tools.fs.workspaceOnly` is enabled. OpenClaw thanks @YLChen-007 for reporting.
