lodash vulnerable to prototype pollution via array-path bypass in `_.unset`, `_.omit`, and `_.pullAt

Impact The .unset, .omit, and .pullAt functions are vulnerable to prototype pollution. The fix for CVE-2025-13465 only guards against string key members, so an attacker can bypass the check by passing array-wrapped path segments. This allows deletion of properties from built-in prototypes such as...
