CVE-2026-60147: Medium severity Oracle Java SE vulnerability
Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE accessible data as well as unauthorized read access to a subset of Java SE accessible data.
Other sources
OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares .foo.com and secret.foo.com literally and returns NAMESAMETYPE, so NameConstraintsExtension.verify does not reject the chain when secret.foo.com is an exact-host exclusion. Later, HostnameChecker interprets the same SAN as a wildcard template and accepts secret.foo.com for .foo.com.

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). 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. Easily exploitable 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 as well as unauthorized read access to a subset 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 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).

Ensure the untrusted code path is not loaded/used via sandboxed Java Web Start applications or sandboxed Java applets (clients running sandboxed Java that load and run untrusted code from the internet rely on the Java sandbox for security for this vulnerability).
- Compensating control
Because successful exploitation can occur via APIs in the affected component (e.g., a web service supplying data to those APIs), restrict and authenticate network access to the affected API endpoints to trusted callers.
