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.

  • GHSA-4564-pvr2-qq4hOpenClaw: Prevent shell injection in macOS keychain credential write2026-02-18ghsa · osvUS

    ## 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.
