Prototype Pollution

protobufjs is a protocol buffer for JavaScript (& TypeScript).

Affected versions of this package are vulnerable to Prototype Pollution. A user-controlled protobuf message can be used by an attacker to pollute the prototype of Object.prototype by adding and overwriting its data and functions. Exploitation can involve:

  1. using the function parse to parse protobuf messages on the fly,

  2. loading .proto files by using load/loadSync functions, or

  3. providing untrusted input to the functions ReflectionObject.setParsedOption and util.setProperty

Note:

  1. This is a different issue from CVE-2022-25878

  2. Users who use this package from npm can rest assured that version 7.2.4 includes the fixed code.

Developers using this package from a different CDN should consider 7.2.5 as the fixed version.

How to fix Prototype Pollution?

Upgrade protobufjs to version 6.11.4, 7.2.4 or higher.

>=6.10.0 <6.11.4 >=7.2.0 <7.2.4
