GHSA-F23M-R3PF-42RH 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 only guards against string key members, so an attacker can bypass the check by passing array-wrapped path segments. This allows deletion of properties fro...

Both paths flow into the same Function constructor sink. Additionally, .template uses assignInWith to merge imports, whi...
