Summary
Miniflux 2: Open Redirect Bypass
Details

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.
