Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated (incomplete) multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final, incomplete code point. This could result in an out-of-bounds read and potential disclosure of adjacent memory contents. This issue is fixed in version 1.26.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","score":5.1},"cwes":["CWE-125"],"references":["https://github.com/uhop/node-re2/commit/9d72042a6a0da5bc523908b04808ea0e23867cc4","https://github.com/uhop/node-re2/issues/272","https://github.com/uhop/node-re2/security/advisories/GHSA-j4r3-hg7j-8chg","https://github.com/uhop/node-re2/security/advisories/GHSA-j4r3-hg7j-8chg"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-71498","score":0.00174,"percentile":0.06785,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j4r3-hg7j-8chg","url":"https://osv.dev/vulnerability/GHSA-j4r3-hg7j-8chg","summary":"node-re2: Out-of-bounds heap read in `replace`/`split` via a `Buffer` ending in a truncated multi-byte UTF-8 character → adjacent heap memory disclosed to JavaScript","modified":"2026-08-06T21:40:58.308038Z","packages":[{"ecosystem":"npm","name":"re2","purl":"pkg:npm/re2","ranges":["<1.26.1"],"fixed":["1.26.1"]}]}],"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).
