How to Fix CVE-2026-27487

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: 2026.2.14 
npm install openclaw@2026.2.14
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-2026-27487, 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 2026.2.14), 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-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. 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 On macOS, the Claude CLI keychain credential refresh path constructed a shell command to write the updated JSON blob into Keychain via `security add-generic-password -w ...`. Because OAuth tokens are user-controlled data, this created an OS command injection risk. The fix avoids invoking a shell by using `execFileSync("security", argv)` and passing the updated keychain payload as a literal argument. ## Affected Packages / Versions - Package: `openclaw` (npm) - Platform: macOS only - Affected versions: `<= 2026.2.13` ## Fix - Patched version: `>= 2026.2.14` (next release) - Fix PR: #15924 - Fix commits (merged to `main`): - `9dce3d8bf83f13c067bc3c32291643d2f1f10a06` - `66d7178f2d6f9d60abad35797f97f3e61389b70c` - `b908388245764fb3586859f44d1dff5372b19caf` Thanks @aether-ai-agent for reporting.
