EUVDB-ID: #VU76823

Risk: Medium

CVSSv4.0: 6.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-21368

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary JavaScript code.

The vulnerability occrures when msgpack5 decodes a map containing a key "__proto__", it assigns the decoded value to __proto__. Object.prototype.__proto__ is an accessor property for the receiver's prototype. A remote user can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
