GHSA-FX83-V9X8-X52W protobuf.js: Prototype injection in generated message constructors

Summary 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...

GHSA-75PX-5XX7-5XC7 protobuf.js: Code generation gadget after prototype pollution

Summary protobufjs used plain objects with inherited prototypes for internal type lookup tables used by generated encode and decode functions. If Object.prototype had already been polluted, those lookup tables could resolve attacker-controlled inherited properties as valid protobuf type...

Prototype Pollution

Overview Affected versions of this package are vulnerable to Prototype Pollution in the code generation. An attacker who has achieved prototype pollution by a different exploit can execute arbitrary JavaScript code by polluting Object.prototype prior to invoking the affected process. Note: This i...

Prototype Pollution

Overview protobufjs is a protocol buffer for JavaScript & TypeScript. Affected versions of this package are vulnerable to Prototype Pollution via schema option path handling. An attacker can perform prototype pollution by supplying a crafted protobuf schema or JSON descriptor whose option paths...
