CWE-1321

This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

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.

All versions of package promisehelpers are vulnerable to Prototype Pollution via the insert function.

All versions of package tiny-conf are vulnerable to Prototype Pollution via the set function.

All versions of package worksmith are vulnerable to Prototype Pollution via the setValue function.

All versions of package safe-object2 are vulnerable to Prototype Pollution via the setter function.
