CVE-2020-24807
The socket.io-file package through 2.0.31 for Node.js relies on client-side validation of file types, which allows remote attackers to execute arbitrary code by uploading an executable file via a modified JSON name field.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
