Affected packages

• npm lodash.mergewith: < 4.6.2 → fixed in 4.6.2

Description

Versions of `lodash.mergewith` before 4.6.2 are vulnerable to prototype pollution. The function `mergeWith` may 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 4.6.2 or later.
