{"apiVersion":"1.0","identifier":"CVE-2026-55185","description":"Miniflux 2 is an open source feed reader. 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.","publishedAt":"2026-08-21T21:17:00","lastModifiedAt":"2026-08-24T20:16:49","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55185","cvssScore":5.1,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00426,"riskScore":0.53,"affectedProduct":"Miniflux","affectedVersions":"<2.3.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-55185","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-55185","en":"https://www.redsauce.net/en/cves/CVE-2026-55185","fr":"https://www.redsauce.net/fr/cves/CVE-2026-55185","pt":"https://www.redsauce.net/pt/cves/CVE-2026-55185","de":"https://www.redsauce.net/de/cves/CVE-2026-55185","sk":"https://www.redsauce.net/sk/cves/CVE-2026-55185","el":"https://www.redsauce.net/el/cves/CVE-2026-55185"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-55185"}}
