An attacker able to make the very first request to the server after startup can poison the router's base path, causing all routes to return 404 for all users (denial of service). The issue is not reachable when baseURL is explicitly configured or on typical managed hosting platforms.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":null}],"references":["https://github.com/better-auth/better-auth/security/advisories/GHSA-569q-mpph-wgww","https://www.vulncheck.com/advisories/better-auth-before-basepath-modification-dos"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-210592","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 2, 2026, 12:15:23 PM","dateUpdated":"Aug 3, 2026, 2:29:35 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
