SCA: security update for oauthlib (GHSA-7984-qgvg-3j9c)

high Tenable Cloud Security Plugin ID 478071

Description

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

- OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. Prior to 4.0.0, the
client_credentials and Resource Owner Password Credentials token grant handlers can authenticate
request.client as one confidential client while retaining an attacker-supplied request.client_id for
validate_grant_type and validate_scopes. A lower-privilege authenticated client can therefore cause grant
and scope authorization to use another client's identity when an application validator relies on the
documented client_id argument, potentially issuing tokens with unauthorized grants or scopes. Validators
that authorize exclusively from request.client may not be affected. This issue is fixed in version 4.0.0.
(CVE-2026-118669)

Solution

Update the oauthlib library and its related packages to version 4.0.0 or later.
