{"id":"CVE-2026-71498","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","details":"node-re2 provides RE2 regular expression bindings for Node.js. 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.","aliases":["GHSA-j4r3-hg7j-8chg"],"modified":"2026-08-09T03:30:30.514032635Z","published":"2026-08-06T21:26:00.771Z","database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71498.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71498.json"},{"type":"ADVISORY","url":"https://github.com/uhop/node-re2/security/advisories/GHSA-j4r3-hg7j-8chg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71498"},{"type":"REPORT","url":"https://github.com/uhop/node-re2/issues/272"},{"type":"FIX","url":"https://github.com/uhop/node-re2/commit/9d72042a6a0da5bc523908b04808ea0e23867cc4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uhop/node-re2","events":[{"introduced":"0"},{"fixed":"9d72042a6a0da5bc523908b04808ea0e23867cc4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.26.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["1.26.0","1.25.2","1.25.1","1.25.0","1.24.1","1.24.0","1.23.3","1.23.2","1.23.1","1.23.0","1.22.3","1.22.2","1.22.1","1.22.0","1.21.5","1.21.4","1.21.3","1.21.2","1.21.1","1.21.0","1.20.12","1.20.11","1.20.10","1.20.9","1.20.8","1.20.7","1.20.6","1.20.5","1.20.4","1.20.3","1.20.2","1.20.1","1.20.0","1.19.2","1.19.1","1.19.0","1.18.3","1.18.2","1.18.1","1.18.0","1.17.8","1.17.7","1.17.6","1.17.5","1.17.4","1.17.3","1.17.2","1.17.1","1.17.0","1.16.0","1.15.9","1.15.8","1.15.7","1.15.6","1.15.5","1.15.4","1.15.3","1.15.2","1.15.1","1.15.0","1.14.0","1.13.0","1.12.1","1.12.0","1.11.0","1.10.5","1.10.4","1.10.3","1.10.2","1.10.1","1.10.0","1.9.0","1.8.4","1.8.3","1.8.2","1.8.1","1.8.0","1.7.0","1.6.2","1.6.1","1.6.0","1.5.0","1.4.1","1.4.0","1.3.3","1.3.2","1.3.1","1.3.0","1.2.0","1.1.1","1.1.0","1.0.0","0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71498.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L"}]}
