CVE-2021-23507

The package object-path-set before 1.0.2 are vulnerable to Prototype Pollution via the setPath method, as it allows an attacker to merge object prototypes into it. Note: This vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-OBJECTPATHSET-607908

Weakness

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
