CVE-2017-15582
In net.MCrypt in the "Diary with lock" (aka WriteDiary) application 4.72 for Android, hardcoded SecretKey and iv variables are used for the AES parameters, which makes it easier for attackers to obtain the cleartext of stored diary entries.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
