    Microsoft IME Japanese Privilege Escalation Vulnerability — Microsoft Input Method Editor (IME) Japanese is a keyboard with Japanese characters that can be enabled on Windows systems as it is included by default (with the default set as disabled). IME Japanese contains an unspecified vulnerability when IMJPDCT.EXE (IME for Japanese) is installed which allows attackers to bypass a sandbox and perform privilege escalation. Listed in the CISA KEV catalog (added 2022-05-25) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~48%. Treat it as real and prioritize remediation over triage.
