Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | fastest-json-copy | <= 1.0.1 | no fix listed |
Details
As written in the advisory (Markdown source, shown as plain text).
fastest-json-copy version 1.0.1 allows an external attacker to edit or add new properties to an object. This is possible because the application does not correctly validate the incoming JSON keys, thus allowing the `__proto__` property to be edited.
