Prototype Pollution in lodash
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | lodash | < 4.17.5 | 4.17.5 |
| RubyGems | lodash-rails | < 4.17.5 | 4.17.5 |
Details
As written in the advisory (Markdown source, shown as plain text).
Versions of `lodash` before 4.17.5 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 `__proto__` causing the addition or modification of an existing property that will exist on all objects.
## Recommendation
Update to version 4.17.5 or later.
