Overview Affected versions of this package are vulnerable to Arbitrary Code Injection via the pbjs static code generation. An attacker can execute arbitrary code by providing crafted schema names that are incorporated into generated JavaScript output, which is then executed or imported by the...

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

Summary A previous fix for unsafe name handling in pbjs static / static-module code generation was incomplete. Affected versions of protobufjs-cli could still emit unsafe JavaScript references when generating static output from crafted JSON descriptor input. The common case of parsing schemas fro...
