"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-305 advisory.

  - Use of Java's default temporary directory for file creation in `FileBackedOutputStream` in Google Guava
    versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the
    machine with access to the default Java temporary directory to be able to access the files created by the
    class. Even though the security vulnerability is fixed in version 32.0.0, we recommend using version
    32.0.1 as version 32.0.0 breaks some functionality under Windows. (CVE-2023-2976)

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