  "details": "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.",
