CVE-2026-71054: Medium severity Oracle Java SE vulnerability
Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 7u511. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE. 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 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

Frequently Asked Questions
Which deployments are most exposed to this issue?
Deployments where Oracle Java SE 7u511 processes attacker-supplied data through affected 2D APIs are exposed, including web services that pass supplied data to those APIs. Client deployments running sandboxed Java Web Start applications or sandboxed Java applets that load untrusted internet-originated code are also affected.
What does an attacker need to exploit it?
An unauthenticated attacker needs network access via one of multiple protocols. The CVSS vector indicates low attack complexity and no required privileges or user interaction.
What is the expected impact of successful exploitation?
Successful exploitation can cause Oracle Java SE to hang or crash repeatedly, resulting in a complete denial of service. The supplied CVSS information also rates integrity and availability impact as low, with no confidentiality impact.
