Overview
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition via the parent process code-sign verification on macOS. An attacker can execute arbitrary code within the context of a signed application by bypassing the code-sign check from a local process, potentially inheriting sensitive permissions and keychain access.
Note: This is only exploitable if fuse-based hardening restricting ELECTRON_RUN_AS_NODE and NODE_OPTIONS to same-signed parents is enabled.
