Prior to 2.3.1, IsRelativePath in internal/urllib/url.go accepts redirect targets containing backslashes because Go URL parsing treats them as path characters. Browser backslash normalization converts them to forward slashes. An unauthenticated attacker can provide such a redirect_url value to the login flow, bypass the relative-path and host checks, and redirect a victim to an attacker-controlled external site. This issue is fixed in version 2.3.1.","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:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.1,"severity":null}],"references":["https://github.com/miniflux/v2/security/advisories/GHSA-m999-j542-5w3r","https://github.com/miniflux/v2/pull/4362","https://github.com/miniflux/v2/commit/c896bafdaa19c3f280b02b1059f84706495f1949","https://github.com/miniflux/v2/releases/tag/2.3.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-64137","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 21, 2026, 8:19:14 PM","dateUpdated":"Aug 24, 2026, 7:46:50 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
