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

  - python-socketio is a Python implementation of the Socket.IO realtime client and server. A remote code
    execution vulnerability in python-socketio versions prior to 5.14.0 allows attackers to execute arbitrary
    Python code through malicious pickle deserialization in multi-server deployments on which the attacker
    previously gained access to the message queue that the servers use for internal communications. When
    Socket.IO servers are configured to use a message queue backend such as Redis for inter-server
    communication, messages sent between the servers are encoded using the `pickle` Python module. When a
    server receives one of these messages through the message queue, it assumes it is trusted and immediately
    deserializes it. The vulnerability stems from deserialization of messages using Python's `pickle.loads()`
    function. Having previously obtained access to the message queue, the attacker can send a python-socketio
    server a crafted pickle payload that executes arbitrary code during deserialization via Python's
    `__reduce__` method. This vulnerability only affects deployments with a compromised message queue. The
    attack can lead to the attacker executing random code in the context of, and with the privileges of a
    Socket.IO server process. Single-server systems that do not use a message queue, and multi-server systems
    with a secure message queue are not vulnerable. In addition to making sure standard security practices are
    followed in the deployment of the message queue, users of the python-socketio package can upgrade to
    version 5.14.0 or newer, which remove the `pickle` module and use the much safer JSON encoding for inter-
    server messaging. (CVE-2025-61765)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2025:3780-1 advisory.

    - CVE-2025-61765: fixed by using json, rather than pickle for serialization (bsc#1251193)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
