Kerentanan Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') pada protobufjs project protobufjs. Skor CVSS 3.1 5.3 (Medium) menurut github.com.

Deskripsi (NVD)

protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs generated message constructors copied enumerable properties from a provided properties object without filtering the __proto__ key. If an application constructed a message from an attacker-controlled plain object, an own enumerable __proto__ property could alter the prototype of that individual message instance. This vulnerability is fixed in 7.5.6 and 8.0.2.
