summary 
lodash vulnerable to Prototype Pollution via array path bypass in `_.unset` and `_.omit`
### Impact

Lodash versions 4.17.23 and earlier are vulnerable to prototype pollution in the `_.unset` and `_.omit` functions. The fix for [CVE-2025-13465](https://github.com/lodash/lodash/security/advisories/GHSA-xxjr-mmjv-4gpg) 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 `Object.prototype`, `Number.prototype`, and `String.prototype`.

The issue permits deletion of prototype properties but does not allow overwriting their original behavior.

### Patches

This issue is patched in 4.18.0.

### Workarounds

None. Upgrade to the patched version.
