Details

Prototype Pollution in lodash 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.
