Prototype Pollution in lodash
Quick fix
GHSA-4xc9-xhrj-v574 — lodash: upgrade to the fixed version with the command below.
npm install lodash@4.17.11Details
Versions of `lodash` before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of `Object` via `{constructor: {prototype: {...}}}` causing the addition or modification of an existing property that will exist on all objects.
## Recommendation
Update to version 4.17.11 or later.
