| Package | Affected versions | Patched versions |
|---|---|---|
| assign-deep | = 1.0.0< 0.4.8 | 0.4.8 |
| assign-deep | ≥ 1.0.0, < 1.0.1< 0.4.8 | 1.0.10.4.8 |
Versions of assign-deep prior to 1.0.1 and 0.4.8 are vulnerable to Prototype Pollution. The assign function fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.
Upgrade to versions 1.0.1, 0.4.8, or later.
