CVSS v3.1
8.7
High
| Vector | AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
protobufjs-cli versions prior to 1.2.1
protobufjs-cli versions prior to 2.0.2
Description
Static code generation via
pbjs can 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 may be written into the output without sufficient sanitization. An attacker who influences the schemas passed to pbjs can cause the generated JavaScript to contain attacker-controlled code, which executes if the generated file is later imported or executed by the application or build process.Recommendations
Update to version 1.2.1.
Update to version 2.0.2.
Avoid running static code generation on untrusted schemas or descriptors.
Validate schema names before code generation and run the process in an isolated environment if untrusted schemas must be accepted.
