The remote Fedora 35 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2022-99c5ddb2ae advisory.

  - In Varnish Cache 7.0.0, 7.0.1, 7.0.2, and 7.1.0, it is possible to cause the Varnish Server to assert and     automatically restart through forged HTTP/1 backend responses. An attack uses a crafted reason phrase of     the backend response status line. This is fixed in 7.0.3 and 7.1.1. (CVE-2022-38150)

  - An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling     attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop,     preventing the Varnish Cache servers from forwarding critical headers to the backend. (CVE-2022-45059)

  - An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2,     and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are     invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1     requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the     Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected. (CVE-2022-45060)

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