CVE-2026-86711
electerm before 5.3.15 exposes 40+ main-process functions through an unvalidated Electron IPC handler with no function-name allowlist or sender validation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
