Description

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.

Recommendation

Update the serialize-javascript package to the latest compatible version. Followings are version details:

  • Affected version(s): < 3.1.0
  • Patched version(s): 3.1.0
