CVE-2026-27487: OpenClaw: Prevent shell injection in macOS keychain credential write

highCVSS 3.1 7.6GHSA-4564-pvr2-qq4h

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.
