An unauthenticated local attacker that can connect to the "CloudMe Sync" client application listening on 127.0.0.1 port 8888 can send a malicious payload causing a buffer overflow condition.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.95%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

An unauthenticated local attacker that can connect to the "CloudMe Sync" client application listening on 127.0.0.1 port 8888 can send a malicious payload causing a buffer overflow condition.
