CVE-2025-30698
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 8u441, 8u441-perf, 11.0.26, 17.0.14, 21.0.6, 24; Oracle GraalVM for JDK: 17.0.14, 21.0.6, 24; Oracle GraalVM Enterprise Edition: 20.3.17 and 21.3.13. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 5.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in the Java SE 2D component allows unauthenticated attackers with network access to compromise Java deployments that run untrusted code (sandboxed applets or Web Start applications). Successful exploitation can result in unauthorized read and write access to a subset of accessible data, plus partial denial of service. The attack is characterized as difficult to exploit.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Java product and versionRun 'java -version' to see the version string. Check if it shows 'Java(TM)' or 'Oracle' to confirm Oracle Java. For GraalVM, run 'java -version' and also check 'java -version' output for GraalVM indicators, or run 'java -Xinternal:version' for detailed build info.Affected if The version output matches one of the affected versions: 1.8.0, 11.0.26, 17.0.14, 21.0.6, 24 for Oracle JRE/JDK; 17.0.14, 21.0.6, 24 for Oracle GraalVM for JDK; 20.3.17 or 21.3.13 for Oracle GraalVM.
-
Confirm Oracle Java distributionRun 'java -version' and examine the vendor line. Oracle Java typically shows 'Oracle Corporation' or contains 'Oracle' in the version output. OpenJDK builds show 'OpenJDK' instead.Affected if The vendor is Oracle or the version string explicitly references Oracle Java, since this vulnerability affects only Oracle Java distributions.
-
Determine if 2D component is in useThe Java 2D component is part of the standard Java runtime. Check if any Java applications use java.awt or javax.imageio packages by reviewing application code or dependencies. The 2D subsystem is loaded when any graphical Java application runs.Affected if The environment runs any Java application that loads the 2D subsystem (any application using AWT or Java 2D graphics), which is part of the standard Java SE installation.
-
Check if untrusted code execution is possibleReview whether the Java deployment runs sandboxed applets (via browser plugin) or Web Start applications. Check browser configurations, Java Control Panel settings (if available), and deployment descriptors for applet or JNLP configurations.Affected if The system runs or has the capability to run untrusted code through sandboxed applets or Web Start applications loaded from the network.
You are affected only if you run Oracle Java (or Oracle GraalVM) at one of the affected versions listed, and your deployment executes untrusted code via applets or Web Start applications using the Java 2D component.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply Oracle's latest Critical Patch Update for the affected Java versions. Additionally, ensure Java deployments do not run untrusted code from the internet, or configure the security sandbox to only load code from trusted sources.
Upgrade to the next available CPU (Critical Patch Update) release: Java 8u451+, Java 11.0.27+, Java 17.0.15+, Java 21.0.7+, Java 24.0.1+; GraalVM for JDK 17.0.15+, 21.0.7+, 24.0.1+; GraalVM Enterprise Edition 20.3.18+, 21.3.14+
- Identify the currently installed Java/JDK version using 'java -version' or 'java --version'
- Identify the installed GraalVM version using 'graalvm --version' if applicable
- For Oracle Java SE 8u441: upgrade to Java 8u451 or later
- For Oracle Java SE 11.0.26: upgrade to Java 11.0.27 or later
- For Oracle Java SE 17.0.14: upgrade to Java 17.0.15 or later
- For Oracle Java SE 21.0.6: upgrade to Java 21.0.7 or later
- For Oracle Java SE 24: upgrade to Java 24.0.1 or later
- For GraalVM for JDK 17.0.14: upgrade to GraalVM for JDK 17.0.15 or later
