Prior to 1.25.2, re2's String.prototype.match implementation with a global RE2 pattern that can match the empty string fails to advance its native matching cursor in lib/match.cc, causing an infinite loop and unbounded native memory growth that blocks the event loop and can exhaust host memory. This issue is fixed in 1.25.2.","published":"2026-07-30T20:07:01.147Z","modified":"2026-09-12T08:07:27.733128Z","cvss":{"score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00188,"percentile":0.08614,"asOf":"2026-09-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"re2","fixedVersion":"1.25.2"}],"fix":{"url":"https://github.com/uhop/node-re2/commit/56293de4fc0914d7bc35f92e98de25b0d9bb417d","label":"uhop/node-re2@56293de"},"references":[{"type":"WEB","url":"https://github.com/uhop/node-re2/releases/tag/1.25.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68499.json"},{"type":"ADVISORY","url":"https://github.com/uhop/node-re2/security/advisories/GHSA-6hxr-mr5r-9836"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68499"},{"type":"FIX","url":"https://github.com/uhop/node-re2/commit/56293de4fc0914d7bc35f92e98de25b0d9bb417d"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-12T08:07:27.733128Z"}}
