Unauthorized data modification through undisclosed JavaFX flaw

Published Apr 16, 2024 · Updated Feb 13, 2025

JavaFX in Oracle Java SE 8u401 allows remote attackers to modify accessible data after a user runs untrusted sandboxed code. Oracle has not disclosed the affected JavaFX function, the untrusted input it processes, or the incorrect operation that enables the modification. The flaw is limited to client deployments that load untrusted code in sandboxed Java Web Start applications or applets and requires user interaction; trusted-code server deployments are not affected.
