Prior to 1.25.2, re2 validates lastIndex against the UTF-8 byte length of a subject but uses it as a UTF-16 code-unit offset in exec, test, match, replace, and split, allowing an attacker-influenced lastIndex on a non-ASCII subject to trigger an out-of-bounds heap read and an uncatchable process crash, with limited heap information disclosure in some cases. This issue is fixed in 1.25.2.","state":0,"publishedAt":"2026-07-30T19:59:55.916+00:00","modifiedAt":"2026-07-31T23:07:18.352+00:00","affected":[{"ecosystem":"Vendor product","name":"node-re2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"uhop\",\n                    \"product\": \"node-re2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.25.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H","score":5.7,"severity":"MEDIUM"}],"references":["https://github.com/uhop/node-re2/security/advisories/GHSA-ff84-5f28-78qj","https://github.com/uhop/node-re2/commit/56293de4fc0914d7bc35f92e98de25b0d9bb417d","https://github.com/uhop/node-re2/releases/tag/1.25.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-67550","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-67550","identifiers":["CVE-2026-67550"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
