AI-suggested

Upgrade Authlib to version 1.8.0 or later, where this vulnerability is fixed. No other mitigation is required as the issue is resolved in the official fix.

Description

Authlib versions prior to 1.8.0 contain an open redirect vulnerability due to improper handling of loopback HTTP exemptions in the is_secure_transport() function. This flaw allows an attacker to bypass TLS requirements by supplying a URL with userinfo that begins with a loopback host, potentially causing cleartext redirection or acceptance of cleartext endpoints. The vulnerability does not affect redirect URI exact matching and does not enable token forgery or user authentication bypass. The issue is fixed in version 1.8.0.
