SCA: security update for Authlib (GHSA-c73q-w75p-j82v)

high Tenable Cloud Security Plugin ID 478082

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 0.15 until 1.9.1, the
 documented ClientConfigurationEndpoint.authenticate_client and
 ClientConfigurationEndpoint.check_permission reference implementations look up a target client from
 request-controlled client_id data and check only whether that target is editable, without verifying that
 request.credential belongs to the target client. Deployments following both examples can allow a client
 holding any valid registration access token to read, modify, or delete another client's registration.
 Changing redirect_uris can enable authorization code or token interception, while deleting registrations
 can deny service to affected clients. This issue is fixed in version 1.9.1. (CVE-2026-116672)

Solution

Update the Authlib library and its related packages to version 1.9.1 or later.
