Summary
An unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 through Update 11 and OpenJDK 7 allows user-assisted remote attackers to bypass the Java security sandbox via unspecified vectors related to JMX.
Risk Assessment
Bypassing the Java sandbox could allow unauthorized code execution in the user's environment, posing a serious security threat.
Recommendation
Update Java SE to the latest available version with security fixes. Limit the use of Java applets and JMX-based applications.

See all- CVE-2026-91382Medium
Vulnerability in Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition (component: 2D) affecting versions such as 8u503, 11.0.32.1, 17.0.20.1, 21.0.12.1 and 21.3.19.1.1. A difficult-to-exploit flaw allows an unauthenticated attacker with network access via multiple protocols to impact data integrity and cause partial denial of service.
- CVE-2026-91381Low
Vulnerability in Oracle Java SE and Oracle GraalVM Enterprise Edition (2D component) affecting versions 8u503, 8u503-perf, and 21.3.19.1.1. A difficult-to-exploit flaw allows an unauthenticated network attacker to modify, insert, or delete some data; also applies to sandboxed Java Web Start/applet deployments.
- CVE-2026-91380Medium
Vulnerability in the Utility component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. This difficult-to-exploit flaw allows an unauthenticated attacker with logon access to the infrastructure to gain unauthorized update, insert, or delete access and unauthorized read access to a subset of data. It can be exploited through APIs in the component, e.g., via a web service supplying data, and also affects Java deployments running untrusted code in a sandbox.
- CVE-2026-91379Medium
Vulnerability in Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition (component: JDK tools) affecting versions such as 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1 and 27. A difficult-to-exploit flaw requires logon to the infrastructure and human interaction and can lead to unauthorized data modification.
- CVE-2026-91375Medium
Vulnerability in Oracle Java SE Libraries component involves difficult-to-exploit attacks requiring logon to the infrastructure and user interaction. Successful exploitation may allow unauthorized creation, deletion, or modification of critical data.
- CVE-2026-91374Medium
Vulnerability in the Serviceability component of Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition allows a difficult-to-exploit network attack. It may result in unauthorized update, insert, or delete access to some data and unauthorized read access to a subset of data.
- CVE-2026-101516Medium
Vulnerability in Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition (component: Libraries) affects multiple supported versions. An easily exploitable flaw allows an unauthenticated attacker with network access via multiple protocols to perform unauthorized update, insert or delete access to some data and unauthorized read access to a subset of data.
- CVE-2016-3552High
Unspecified vulnerability in Oracle Java SE 8u92 allows local users to affect confidentiality, integrity, and availability via vectors related to Install.
- CVE-2016-3449High
Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Deployment.
- CVE-2015-4901High
An unspecified vulnerability in Oracle Java SE 8u60 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to JavaFX.
Original NVD description (English source)
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 through Update 11, and OpenJDK 7, allows user-assisted remote attackers to bypass the Java security sandbox via unspecified vectors related to JMX, aka "Issue 52," a different vulnerability than CVE-2013-1490.
