Prior to 7.5.6 and 8.0.2, protobufjs could recurse without a depth limit while decoding nested protobuf data. This affected both skipping unknown group fields and generated decoding of nested message fields. A crafted protobuf binary payload could cause the JavaScript call stack to be exhausted during decoding. This vulnerability is fixed in 7.5.6 and 8.0.2.","published":"2026-05-13T14:39:09.791Z","modified":"2026-08-08T03:30:38.391094681Z","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":0.0058,"percentile":0.44486,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"protobufjs","fixedVersion":"7.5.6"},{"ecosystem":"npm","name":"protobufjs","fixedVersion":"8.0.2"}],"fix":null,"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-44289.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:42815"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-44289"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44289.json"},{"type":"ADVISORY","url":"https://github.com/protobufjs/protobuf.js/security/advisories/GHSA-685m-2w69-288q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44289"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2477130"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:30:38.391094681Z"}}
