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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":null}],"references":["https://github.com/le0pard/re2js/security/advisories/GHSA-gg6h-894w-4m9c","https://github.com/le0pard/re2js/pull/59","https://github.com/le0pard/re2js/commit/dfdd947785dfa113bdc97416375c246a39458395","https://github.com/le0pard/re2js/releases/tag/2.8.7"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112268","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 28, 2026, 5:14:15 PM","dateUpdated":"Oct 28, 2026, 5:14:15 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
