CVE-2026-111377
FreeRDP from 2.0.0 before 3.32.0 contains an unbounded reassembly vulnerability in WTSProcessChannelData that fails to enforce cumulative fragment limits.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
