Improper checks of file names allows remote attackers to upload files without any extension (even if the application was configured to accept files only with a defined set of extensions).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
