{"id":"CVE-2026-48712","aliases":["GHSA-wcpc-wj8m-hjx6"],"url":"https://o3.security/vulnerability/CVE-2026-48712","summary":"protobufjs: Denial of service through unbounded Any expansion during JSON conversion","details":"protobufjs compiles protobuf definitions into JavaScript (JS) functions. 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.","published":"2026-06-22T16:21:21.506Z","modified":"2026-08-12T03:51:39.973573097Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.0046,"percentile":0.37644,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"protobufjs","fixedVersion":"7.6.1"},{"ecosystem":"npm","name":"protobufjs","fixedVersion":"8.4.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48712.json"},{"type":"ADVISORY","url":"https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-wcpc-wj8m-hjx6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48712"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.973573097Z"}}
