Both paths flow into the same `Function()` constructor sink.\n\nWhen an application passes untrusted input as `options.imports` key names, an attacker can inject default-parameter expressions that execute arbitrary code at template compilation time.\n\nAdditionally, `_.template` uses `assignInWith` to merge imports, which enumerates inherited properties via `for..in`. If `Object.prototype` has been polluted by any other vector, the polluted keys are copied into the imports object and passed to `Function()`.\n\n### Patches\n\nUsers should upgrade to version 4.18.0.\n\nThe fix applies two changes:\n1. Validate `importsKeys` against the existing `reForbiddenIdentifierChars` regex (same check already used for the `variable` option)\n2. Replace `assignInWith` with `assignWith` when merging imports, so only own properties are enumerated\n\n### Workarounds\n\nDo not pass untrusted input as key names in `options.imports`.
