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":"2026-08-21T20:19:14.122+00:00","modifiedAt":"2026-08-24T19:46:50.85+00:00","affected":[{"ecosystem":"Vendor product","name":"v2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"miniflux\",\n                    \"product\": \"v2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.3.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"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":"MEDIUM"}],"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://www.cve.org/CVERecord?id=CVE-2026-55185","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55185","identifiers":["CVE-2026-55185"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
