It is, therefore, affected by a vulnerability.

  - An authorization vulnerability in the Journal module could allow an authenticated user to add a like to
    a private journal post they are not authorized to access. Sites using the Journal module should upgrade to
    a patched release to ensure journal privacy settings are consistently enforced. A vulnerability was
    identified in the Journal module where authorization checks were not consistently enforced when recording
    likes on private journal posts. Under certain conditions, an authenticated user with minimal privileges
    could add a like to a private journal entry despite not having permission to view it. While the
    vulnerability does not expose the contents of private journal posts or allow modification of their
    content, it may create visible interactions associated with private activity, potentially causing
    confusion or giving the appearance that unauthorized users were able to participate in private
    discussions, which could be leveraged to help with a social engineering attack. (GHSA-r4c4-vmqp-vxf2)

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