CVE-2026-27487

OpenClaw: Prevent shell injection in macOS keychain credential write

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.
