Details

Insecure serialization leading to RCE in serialize-javascript serialize-javascript prior to 3.1.0 allows remote attackers to inject arbitrary code via the function "deleteFunctions" within "index.js". An object such as `{"foo": /1"/, "bar": "a\"@__R-<UID>-0__@"}` was serialized as `{"foo": /1"/, "bar": "a\/1"/}`, which allows an attacker to escape the `bar` key. This requires the attacker to control the values of both `foo` and `bar` and guess the value of `<UID>`. The UID has a keyspace of approximately 4 billion making it a realistic network attack.
