CVE-2019-4553
IBM API Connect V5.0.0.0 through 5.0.8.7iFix3 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
