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.\n\n## Impact\n\nAn attacker who can provide or influence schemas passed to `pbjs` may be able to cause generated JavaScript output to contain attacker-controlled code. The injected code would run if the generated file is later executed or imported by the application or build process.\n\nThis affects the protobufjs CLI static code generation path. Applications that only use trusted schemas, or that do not execute generated output from untrusted schemas, are not directly affected.\n\n## Preconditions\n\n- The application or build process must run `pbjs` static code generation on a schema or JSON descriptor influenced by an attacker.\n- The attacker-controlled input must contain crafted schema names that reach generated JavaScript output.\n- The generated JavaScript file must subsequently be executed, imported, or otherwise evaluated.\n\n## Workarounds\n\nDo not run affected versions of `pbjs` static code generation on untrusted schemas or descriptors. If untrusted schemas must be accepted, validate schema names before code generation and run generation in an isolated environment.","state":0,"publishedAt":"2026-05-12T15:06:22+00:00","modifiedAt":"2026-09-10T03:50:45.7962088+00:00","affected":[{"ecosystem":"npm","name":"protobufjs-cli","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.2.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"protobufjs-cli","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.0.0"},{"kind":"fixed","version":"2.0.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-6r35-46g8-jcw9","https://nvd.nist.gov/vuln/detail/CVE-2026-44295","https://github.com/protobufjs/protobuf.js","https://github.com/protobufjs/protobuf.js/releases/tag/protobufjs-cli-v1.2.1","https://github.com/protobufjs/protobuf.js/releases/tag/protobufjs-cli-v2.0.2"],"sourceUrl":"https://github.com/advisories/GHSA-6r35-46g8-jcw9","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-6r35-46g8-jcw9","identifiers":["GHSA-6r35-46g8-jcw9","CVE-2026-44295"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
