"The version of fluent-bit / nghttp2 / nodejs / nodejs18 installed on the remote Azure Linux 3.0 host is prior to tested
version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-28182 advisory.

  - nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior
    to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is
    reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2
    v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
    There is no workaround for this vulnerability. (CVE-2024-28182)

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