CVE-2025-30749Network attack vector

Unauthenticated runtime takeover via sandboxed untrusted code

Published Jul 15, 2025 · Updated Feb 26, 2026

Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition allow remote attackers to take over affected runtimes. Oracle identifies the flaw only in the 2D component and has not disclosed the operation that mishandles untrusted input. Exploitation requires a deployment that loads untrusted code and relies on the Java sandbox; trusted-code-only server deployments are not affected.
