CVE-2026-47021

Name of the Vulnerable Software and Affected Versions Oracle Java SE versions 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, and 26.0.1 Oracle GraalVM for JDK versions 17.0.19 and 21.0.11 Oracle GraalVM Enterprise Edition version 21.3.18

Description A flaw in the 2D component allows an unauthenticated attacker with network access via multiple protocols to compromise the system. This can result in a partial denial of service (partial DOS). The issue can be exploited through APIs in the affected component, such as via a web service providing data to those APIs. It also impacts Java deployments that load and run untrusted code, such as sandboxed Java Web Start applications or sandboxed Java applets, which rely on the Java sandbox for security.

Recommendations Update Oracle Java SE to versions 8u491, 11.0.32, 17.0.20, 21.0.12, 25.0.4, or 26.0.2. Update Oracle GraalVM for JDK to versions 17.0.20 or 21.0.12. Update Oracle GraalVM Enterprise Edition to a version newer than 21.3.18.
