In the encryption algorithm used by this encryption class, the cipher is initialized with a hardcoded key and IV.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
