SCA: security update for authlib (GHSA-jj7h-c3hg-m23x)

low Tenable Cloud Security Plugin ID 477610

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Authlib is a Python library which builds OAuth and OpenID Connect servers. From 0.13 until 1.8.0,
 authlib.common.security.is_secure_transport() uses a textual prefix comparison for loopback HTTP
 exemptions, so a URL whose userinfo begins with a loopback host can be accepted even when its parsed host
 is an external non-loopback system. An external party able to supply a URL to OIDC RP-Initiated Logout
 registration, authorization-server metadata validation, or another call site can bypass the TLS-required
 guard and cause cleartext redirection or acceptance of cleartext endpoints. The issue does not bypass
 redirect URI exact matching and does not by itself forge tokens or authenticate users. The vulnerable
 authlib.common.security.is_secure_transport() implementation in authlib/common/security.py misinterprets
 the userinfo component before OIDC RP-Initiated Logout dynamic client registration and other consumers
 enforce transport security. This issue is fixed in version 1.8.0. (CVE-2026-114614)

Solution

Update the authlib library and its related packages to version 1.8.0 or later.
