Description

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: `= 2026.2.14` (next release) • Fix PR: #15924 • Fix commits (merged to `main`): • `9dce3d8bf83f13c067bc3c32291643d2f1f10a06` • `66d7178f2d6f9d60abad35797f97f3e61389b70c` • `b908388245764fb3586859f44d1dff5372b19caf` Thanks @aether-ai-agent for reporting.
