CVE-2026-61308 is an authentication-handling vulnerability in the Networking component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition, also affecting OpenJDK-based distributions. An unauthenticated attacker with HTTP network access can potentially obtain critical data or all data accessible to the affected Java runtime. Affected Oracle versions include Java SE 8u501, 11.0.32, 17.0.20, 21.0.12, 25.0.4, and 26.0.2; GraalVM for JDK 17.0.20 and 21.0.12; and GraalVM Enterprise Edition 21.3.19. Exploitation is described as difficult and can occur when attacker-controlled data reaches Networking APIs, including through a web service. Deployments executing untrusted code in sandboxed Java Web Start applications or applets are also affected. The precise vulnerable function and authentication failure mechanism are not specified.

A vulnerability affecting Java 11 OpenJDK packages covered by SUSE advisory SUSE-SU-2026:4515-1. The advisory describes the fix as enhancing HTTP connections. This CVE is identified as the source of the plugin's CVSS scoring, whose vectors indicate a network-accessible confidentiality impact with high attack complexity. The update upgrades OpenJDK to jdk-11.0.32.1+1.
A Networking component vulnerability that allows an unauthenticated attacker using HTTP to access critical data or all data accessible to affected Java products, with potential impact beyond those products. Exploitation is described as difficult and can occur through affected APIs or deployments that execute untrusted code and rely on the Java sandbox. Amazon Corretto 17 versions before 17.0.20.10.1 are affected. Nessus performed version-based detection rather than exploit testing.
A network-reachable vulnerability affecting Alma Linux 9.6, rated Moderate by the advisory. Successful exploitation requires high attack complexity and can result in high confidentiality impact across a changed scope; no known exploit is available.
A moderate-severity network-accessible vulnerability affecting Rocky Linux 9.6 packages covered by the advisory. It requires high attack complexity, no privileges or user interaction, can affect a changed security scope, and has high confidentiality impact. No known public exploit is available according to the plugin.
