QID 980727

QID 980727: Nodejs (npm) Security Update for serialize-javascript (GHSA-hxcc-f52p-wc94)

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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as Critical - 8.1 severity.

CVSS V2 rated as High - 6.8 severity.
