NVD Description
Note: Versions mentioned in the description apply only to the upstream miniflux package and not the miniflux package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
