If an unsanitized source object contained an enumerable `__proto__` property, it could extend the native `Object.prototype`. ## Affected packages - `jquery >= 1.1.4, < 3.4.0` - `jquery-rails < 4.3.4` - `jQuery >= 1.1.4, < 3.4.0` - `django >= 2.0a1, < 2.1.9` - `django >= 2.2a1, < 2.2.2` - `org.webjars.npm:jquery >= 1.1.4, < 3.4.0` - `maximebf/debugbar < 1.19.0` ## Remediation Upgrade to a patched release: - `jquery 3.4.0` - `jquery-rails 4.3.4` - `jQuery 3.4.0` - `django 2.1.9` - `django 2.2.2` - `org.webjars.npm:jquery 3.4.0` - `maximebf/debugbar 1.19.0`
