CVE-2023-22043Network attack vector

Unauthenticated modification of critical application data

Published Jul 18, 2023 · Updated Feb 13, 2025

Integrity compromise in Oracle Java SE 8u371 JavaFX allows remote attackers to modify critical application data via multiple protocols. Oracle identifies JavaFX as the affected component but has not published the code locus or incorrect operation on untrusted input. Exploitation requires a client to load untrusted code in a sandboxed Java Web Start application or applet; trusted-code server deployments are not affected.
