Miniflux 2: Open Redirect Bypass

5.1 MediumFix available

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.

Open Redirect Bypass in miniflux-v2

Summary

The URL restrictions in miniflux-v2 can be bypassed by attackers, leading to an open redirect vulnerability.

Details

Normally, the redirect URL needs to be validated using IsRelativePath.

<img width="1728" height="1386" alt="QQ20260526-175356-26-1" src="https://github.com/user-attachments/assets/b481845a-8744-41f7-b27a-526c7ac92e03" />

There are some security measures in place, such as requiring relative paths, prohibiting host and schema entries, and rejecting proof-of-concept (PoC) entries like //fushuling.com. However, these measures can still be bypassed.

<img width="1911" height="804" alt="QQ20260526-175836-26-2" src="https://github.com/user-attachments/assets/90353c7f-7247-4453-a781-159361de13d6" />

For a proof-of-concept (PoC) like /\fushuling.com, it lacks host and netloc fields and doesn't start with //, but during the actual browser redirection, the backslash is automatically parsed as a forward slash, ultimately redirecting to the external address https://fushuling.com, thus bypassing existing protections.

For PoCs like //fushuling.com, the existing logic successfully detects and resolves to /unread, effectively preventing attacks.

However, when the attacker specified the redirect URL as /\fushuling.com, the URL successfully bypassed the detection and set the location to /\fushuling.com.
