The version of golang installed on the remote host is prior to 1.18.9-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2131 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- The go command may generate unexpected code at build time when using cgo. This may result in unexpected
behavior when running a go program which uses cgo. This may occur when running an untrusted module which
contains directories with newline characters in their names. Modules which are retrieved using the go
command, i.e. via go get, are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off,
may be affected). (CVE-2023-29402)
