Description
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: ImageIO). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. 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. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also 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. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

Impact

Vulnerability in the ImageIO component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition permits an unauthenticated attacker with network access to perform unauthorized update, insert, or delete operations against data accessible to the Java or GraalVM runtime. The flaw can be triggered through image processing APIs, for example from a web service that supplies JPEG data to the application, and also applies to sandboxed client deployments that load untrusted code. The impact is strictly on integrity, resulting in potential data modification without disabling services or escalating privileges. This vulnerability involves both unauthorized access control (CWE‑284) and memory corruption via out‑of‑bounds writes (CWE‑787).

Affected Systems

Oracle GraalVM Enterprise Edition 21.3.18, Oracle GraalVM for JDK 17.0.19 and 21.0.11, and Oracle Java SE 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1 are affected.

Risk and Exploitability

The CVSS v3.1 base score of 3.7 combined with an EPSS score of less than 1% indicates low severity but a very low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog. The attack can be carried out remotely via network protocols; no authentication or elevated privileges are required, so an attacker only needs network reach to the vulnerable system to exploit the flaw.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Oracle Java SE, Oracle GraalVM for JDK, or Oracle GraalVM Enterprise Edition to the latest patched release that removes the ImageIO issue.
  • If an upgrade is not possible, limit ImageIO JPEG decoding to trusted data sources only or disable JPEG handling in the affected applications.
  • Implement strict input validation or sanitization for all JPEG files before passing them to ImageIO APIs.
