Prototype Pollution in mout (GHSA-pc58-wgmc-hfjr)

Description

This affects all versions of package mout. The deepFillIn function can be used to ‘fill missing properties recursively’, while the deepMixIn ‘mixes objects into the target object, recursively mixing existing child objects as well’. In both cases, the key used to access the target object recursively is not checked, leading to a Prototype Pollution.

Recommendation

Update the mout package to the latest compatible version. Followings are version details:

• Affected version(s): < 1.2.3
• Patched version(s): 1.2.3
