CVSS 3.1
5.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:NCVE-2023-0842
Medium (5.3) in xml2js project xml2js. EPSS 1.4% chance of exploitation in the next 30 days. Fixed in xml2js 0.5.0.
xml2js version 0.4.23 allows an external attacker to edit or add new properties to an object. This is possible because the application does not properly validate incoming JSON keys, thus allowing the __proto__ property to be edited.
