Version Disclosure (Lodash)

Bug description

Impact An attacker might use the disclosed information to harvest specific security vulnerabilities for the version identified.

Hello @Harmanpreet-96 I couldn't find where is the version exposed, could you please provide us with exact reproduction steps?

For Version Disclosure (Lodash), the commands below can be executed on the browser’s console. '.templateSettings.imports..templateSettings.imports._.VERSION'

@Harmanpreet-96 that's not a valid snippet of code to execute so your instructions are not reproducible. Can you please specify more exactly what to execute in the developer tools console that will display the Lodash version?

@JMach1, FYI, this finding comes from an Invicti Enterprise security scan.

I am not able to add an underscore in front of this command.

.templateSettings.imports..templateSettings.imports._.VERSION

[brsolomon-deloitte]

.templateSettings.imports..templateSettings.imports..VERSION

@Harmanpreet-96 Again: that is not a valid variable name. What specifically are you suggesting?

Any updates?

Resolved console disclosure of the "underscore" variable by updating lodash imports. Replaced:

import { isEqual } from "lodash";

with:

import isEqual from "lodash/isEqual";

The issue was resolved for me
