protobufjs-cli: Code injection in pbjs static output from crafted schema names

Published May 13, 2026 CVSS 3.1 · 8.7 High EPSS < 1% KEV · Not listed
Description
protobufjs-cli is the command line add-on for protobuf.js. Prior to 1.2.1 and 2.0.2, pbjs static code generation could emit unsafe JavaScript identifiers derived from schema-controlled names. When generating static JavaScript from a crafted schema or JSON descriptor, certain namespace, enum, service, or derived full names could be written into the generated output without sufficient sanitization. This vulnerability is fixed in 1.2.1 and 2.0.2.
