Prior to 7.6.1 and 8.4.1, protobufjs could recurse without a depth limit while converting decoded messages to plain objects or JSON. This affected generated toObject() conversion and the custom google.protobuf.Any JSON conversion path. A crafted protobuf binary payload containing deeply nested Any values could cause the JavaScript call stack to be exhausted during conversion to JSON. This vulnerability is fixed in 7.6.1 and 8.4.1.","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:H","score":7.5},"cwes":["CWE-674"],"references":["https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-wcpc-wj8m-hjx6"],"products":["protobufjs_project:protobufjs"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-48712","score":0.0046,"percentile":0.396,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wcpc-wj8m-hjx6","url":"https://osv.dev/vulnerability/GHSA-wcpc-wj8m-hjx6","summary":"protobufjs: Denial of service through unbounded Any expansion during JSON conversion","modified":"2026-09-10T03:51:09.675279620Z","packages":[{"ecosystem":"npm","name":"protobufjs","purl":"pkg:npm/protobufjs","ranges":["<7.6.1"],"fixed":["7.6.1"]},{"ecosystem":"npm","name":"protobufjs","purl":"pkg:npm/protobufjs","ranges":[">=8.0.0 <8.4.1"],"fixed":["8.4.1"]}]}],"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).
