Tauri HTTP Plugin HTTP 3xx Redirect Bypass

Publication date: 2026-09-22

Last updated on: 2026-09-22

Assigner: JFrog

Description
The Tauri HTTP plugin validates requested URLs against the application's configured scope allowlist only once, on the initial request. When the remote server responds with an HTTP 3xx redirect, reqwest follows the redirect internally without re-checking the new target URL against the scope. This allows an attacker who controls an allowed URL (or finds an open redirect on an allowed host) to reach disallowed destinations such as cloud metadata endpoints, localhost services, or internal network hosts.

Executive Summary

This vulnerability affects the Tauri HTTP plugin. It only checks if a requested URL is allowed once, during the initial request. If the server responds with a redirect (HTTP 3xx), the plugin follows the redirect without verifying if the new URL is permitted. This allows attackers to bypass restrictions by redirecting to unauthorized destinations like localhost, internal networks, or cloud metadata endpoints.

Impact Analysis

An attacker could exploit this to access sensitive internal services or data by tricking the application into following a malicious redirect. This might lead to unauthorized access, data leaks, or exposure of internal network resources if the application interacts with allowed but vulnerable services.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. If exploited, it may result in data breaches, non-compliance with data protection regulations, and potential legal consequences for organizations handling protected information.

Mitigation Strategies

Update the Tauri HTTP plugin to version 2.7.0 or later and enable the scopeRedirects configuration option to enforce URL scope checks during every redirect step. This prevents unauthorized redirects to disallowed destinations like localhost or internal hosts.
