The version of curl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2004 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of curl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2024-2004 advisory.
- When a protocol selection parameter option disables all protocols without adding any then the default set
of protocols would remain in the allowed set due to an error in the logic for removing protocols. The
below command would perform a request to curl.se with a plaintext protocol which has been explicitly
disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols
disables the entire set of available protocols, in itself a command with no practical use and therefore
unlikely to be encountered in real situations. The curl security team has thus assessed this to be low
severity bug. (CVE-2024-2004)
