Title
UpSignOn < 7.19.0 Sensitive Data Exposure in Process Memory after Lock
Summary
UpSignOn for Windows before 7.19.0 contains a sensitive data exposure vulnerability that allows local attackers to recover cleartext vault data from process memory even after the application has been locked. Attackers can use the PROCESS_VM_READ permission to read the memory space of UpSignOn.exe and extract sensitive fields including entry names, URLs, usernames, passwords, TOTP secrets, and notes.
