Libcurl and curl security vulnerability

As a user of the SeNtinel Application Platform (SNAP-V9) for evaluating Sentinel data in our agency, I have the following question about the following warning from the warning and information service of CERT Nord, it says:
“… based on information on and also in other sources (see links below) we would like to forward a recommendation from the Dataport SOC. Unfortunately, no details of the vulnerability are currently known, but the founder of the cURL project describes the vulnerability as “the worst security hole in a long time. The cURL and libcurl components are widespread and used in many applications. cURL is a tool used by numerous applications to execute web requests.”

Notes from the service provider Tenable:

Through scanning our systems, cURL files and its libcurl library also appeared in SNAP (version not recognized?).
