From 2.2.0 until 2.8.7, enabling LOOKBEHINDS and using repeated matching through matcher().find(), matchAll(), split(), or matcher().replaceAll() can cause quadratic total work. Machine.match restarts lookbehind scanning from offset zero for each requested start position, while Matcher-based APIs request capture slots that prevent the early exit used for captureless matching. Dense matches therefore repeatedly rescan the input, allowing attacker-influenced text to monopolize a single-threaded worker and deny service. This issue is fixed in version 2.8.7.","state":0,"publishedAt":"2026-10-28T18:17:14.303+00:00","modifiedAt":"2026-10-29T16:19:37.75+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/le0pard/re2js/commit/dfdd947785dfa113bdc97416375c246a39458395","https://github.com/le0pard/re2js/pull/59","https://github.com/le0pard/re2js/releases/tag/2.8.7","https://github.com/le0pard/re2js/security/advisories/GHSA-gg6h-894w-4m9c"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-116795","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-407","CWE-1333"],"productCriteria":[],"sourceDates":{"published":"2026-10-28T18:17:14.303","lastModified":"2026-10-29T16:19:37.750"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
