CVE-2026-18915

OTP secret disclosure via pkexec command arguments

Published Aug 6, 2026 · Updated Aug 6, 2026

Sensitive-information exposure in eta-otp-lock before 1.0.4 allows local users to read an OTP secret from a process command line. MainWindow.py supplies the generated or imported secret as the final argument in a pkexec call to actions.py save, making it visible in process listings. Exploitation requires a low-privileged local user to inspect the transient command line while another user creates or imports a secret; the exposed seed permits generation of that user's OTP codes.
