protobufjs compiles protobuf definitions into JavaScript (JS) functions.
Published Apr 18, 2026 · updated Sep 9, 2026 · protobufjs project protobufjs
protobufjs compiles protobuf definitions into JavaScript (JS) functions. In versions prior to 8.0.1 and 7.5.5, attackers can inject arbitrary code in the "type" fields of protobuf definitions, which will then execute during object decoding using that definition. Versions 8.0.1 and 7.5.5 patch the issue.
