CVE-2026-60164Network attack vector

Sandboxed client data disclosure

Published Jul 21, 2026 · Updated Jul 21, 2026

Information disclosure in JavaFX in Oracle Java SE 8u491 allows remote attackers to read a subset of accessible data via untrusted code. Oracle has not disclosed the faulty JavaFX code path or the operation that exposes data, beyond classifying it as a protection-mechanism failure. Exploitation requires user interaction in a sandboxed Java Web Start application or applet that loads untrusted code; trusted-code server deployments are not affected.
