Credential disclosure via readable plaintext process memory
Published Jul 12, 2023 · Updated Jun 9, 2025
Information disclosure in Keeper Password Manager Desktop 16.10.2 and KeeperFill 16.5.4 allows local users to read plaintext credentials. The published Windows proof of concept reads private committed memory from Keeper renderer processes and extracts credential JSON and master-password data. Keeper disputes the issue because process memory is already readable to a local attacker during a logged-in session and attributes post-logout remnants to browser memory management.
