The version of thunderbird installed on the remote host is prior to 78.10.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1644 advisory.

  • Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network’s hosts as well as services running on the user’s local machine. This vulnerability affects Firefox < 85. (CVE-2021-23961)

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