CVE-2025-50063

Local privilege escalation via redirected installer deletion

Published Jul 15, 2025 · Updated Feb 26, 2026

Privilege escalation in Oracle Java SE 8u451 allows local users to take over Java through the client installation process. The installer deletes the baseimagefam8 file through a path that permits attacker-controlled file-system redirection. A low-privileged logon and interaction by another person are required, after which the local user gains the installer's elevated authority.
