Live › vulnerability › CVE-2026-91410
Go to dashboardA flaw in the Libraries component of Oracle Java SE can be triggered remotely over several protocols without credentials, through services that pass data to the affected APIs. A successful attack causes a partial denial of service, with no confidentiality or integrity impact.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-23 21:57 UTC. All times on this page are UTC.
Any server or service running an affected Oracle Java SE or GraalVM build that exposes network endpoints which feed untrusted data into the affected Libraries APIs is exposed. Client deployments that run untrusted code in Java Web Start or applet sandboxes are also named in the advisory. Teams running only patched builds or no Java at all can skip it.
No product ranges from the sources yet.
java -version and compare the build against the affected releases listed in the advisory: Java SE 8u503, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, and GraalVM for JDK 17.0.20.1 and 21.0.12.1.java -version on each host and container image that runs a JVM, including bundled runtimes inside applications.Each row is the first time that source carried this signal.

Vulnerability in Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. 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 partial denial of service (partial 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
