CVE-2022-25354

Estado: ModificadaCrítica (9.8)—

The package set-in before 2.0.3 are vulnerable to Prototype Pollution via the setIn method, as it allows an attacker to merge object prototypes into it. **Note:** This vulnerability derives from an incomplete fix of [CVE-2020-28273](https://security.snyk.io/vuln/SNYK-JS-SETIN-1048049)
