CVE-2026-27487
OpenClaw: Prevent shell injection in macOS keychain credential write
OpenClaw is a personal AI assistant. In versions 2026.2.13 and below, when using 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. This issue has been fixed in version 2026.2.14.

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.
