Prior to 7.5.6 and 8.0.2, protobufjs generated JavaScript property accessors from schema-controlled field and oneof names. Certain control characters in field names were not escaped before being embedded into generated function bodies. A crafted schema or JSON descriptor could therefore cause generated encode, decode, verify, or conversion functions to fail during compilation. This vulnerability is fixed in 7.5.6 and 8.0.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-20"],"references":["https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-2pr8-phx7-x9h3"],"products":["protobufjs_project:protobufjs"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-44294","score":0.00431,"percentile":0.37402,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2pr8-phx7-x9h3","url":"https://osv.dev/vulnerability/GHSA-2pr8-phx7-x9h3","summary":"protobuf.js: Denial of service from crafted field names in generated code","modified":"2026-09-10T03:51:04.232420559Z","packages":[{"ecosystem":"npm","name":"protobufjs","purl":"pkg:npm/protobufjs","ranges":["<7.5.6"],"fixed":["7.5.6"]},{"ecosystem":"npm","name":"protobufjs","purl":"pkg:npm/protobufjs","ranges":[">=8.0.0 <8.0.2"],"fixed":["8.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
