CVE-2024-33900Public exploit

Cleartext credential recovery from process memory dumps

Published May 20, 2024 · Updated Feb 13, 2025

Cleartext credential exposure in KeePassXC 2.7.7 allows local users with victim-level privileges to recover passwords from a memory dump. KeePassXC leaves the master password as a UTF-16 string in Qt-managed process memory after the database is unlocked, allowing string searches of a captured dump. Exploitation requires access sufficient to dump the victim's process and is most reliable while the database is open; KeePassXC disputes treating this design constraint as a vulnerability.
