CVE-2026-114820: Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE).

CriticalCVSS 9.1 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: java-21-openjdk (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1; java-21-openjdk-demo (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1; java-21-openjdk-demo-fastdebug (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1.

Low priority for now. Upgrade to java-21-openjdk (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1; java-21-openjdk-demo (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1; java-21-openjdk-demo-fastdebug (AlmaLinux:10) 1:21.0.13.0.9-1.2.el10.alma.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u511-b32, 8u511-perf-b32, 11.0.33.0.2, 17.0.21.0.2, 21.0.13.0.2, 25.0.5.0.2, 27.0.1.0.2; Oracle GraalVM for JDK: 17.0.21.0.2 and 21.0.13.0.2; Oracle GraalVM Enterprise Edition: 21.3.20.0.2. 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 creation, deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as unauthorized access to critical data or complete access to all 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 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
