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)

The remote Redhat Enterprise Linux 10 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2026:98641 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,     classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to     many system calls and libraries, as well as to various windowing systems.

    Security Fix(es):

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:1328 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-118669:
