Use of hardcoded cryptographic key in BlowFish.cpp in hMailServer 5.8.6 and 5.6.9-beta allows attacker to decrypt passwords used in database connections from hMailServer.ini config file.
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
