Oracle Java SE Data Access Vulnerability

Publication date: 2026-07-21

Last updated on: 2026-08-03

Assigner: Oracle

Description

Vulnerability in Oracle Java SE (component: Scripting). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf and 11.0.31. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Java SE accessible data as well as unauthorized access to critical data or complete access to all Oracle Java SE 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 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).

Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Java SE's Scripting component affecting versions 8u491, 8u491-perf, and 11.0.31. It allows unauthenticated attackers with network access to potentially compromise the system through multiple protocols. Successful exploitation could lead to unauthorized data creation, deletion, or modification, as well as unauthorized access to critical data.

Detection Guidance

This vulnerability affects Oracle Java SE versions 8u491, 8u491-perf, and 11.0.31. Detection involves checking installed Java versions and monitoring for suspicious API usage in web services or Java applications. Use commands like 'java -version' to check versions and review application logs for untrusted code execution.

Impact Analysis

If exploited, this vulnerability could allow attackers to access, modify, or delete sensitive data within Oracle Java SE environments. Systems running untrusted Java code, such as web applications or applets, are particularly at risk if they rely on the Java sandbox for security.

Compliance Impact

This vulnerability allows unauthorized access to critical data, which could lead to unauthorized creation, deletion, or modification of sensitive information. Such breaches could violate GDPR's data integrity and confidentiality requirements, potentially resulting in significant fines. For HIPAA, unauthorized access to protected health information could compromise compliance with the Security Rule, leading to penalties and reputational damage.

Mitigation Strategies

Update Oracle Java SE to versions 8u501 or 11.0.32 or later to address the vulnerability. Remove or disable any untrusted Java applications running in sandboxed environments like Java Web Start or applets.
