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`.\n\nThe issue permits deletion of prototype properties but does not allow overwriting their original behavior.\n\n### Patches\n\nThis issue is patched in 4.18.0.\n\n### Workarounds\n\nNone.
