Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in Oracle Java SE (component: Scripting). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf and 11.0.31. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Java SE accessible data as well as unauthorized access to critical data or complete access to all Oracle Java SE 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 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-04.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Recommended fix Moderate confidence

Oracle Java SE 8u511 or later / Java SE 11.0.24 or later (or the latest available Oracle Java SE LTS release)

  1. 1. Identify the exact Java SE version currently installed by running `java -version`
  2. 2. Download the latest Oracle Java SE JDK/JRE from the official Oracle website (https://www.oracle.com/java/technologies/downloads/)
  3. 3. Install the updated Java SE version following Oracle's installation documentation
  4. 4. Update JAVA_HOME environment variable to point to the new installation path
  5. 5. Verify the new version is active by running `java -version`
  6. 6. Update any build tools, CI/CD pipelines, and application servers that reference the old Java installation path
  7. 7. Test all applications that depend on Java to ensure compatibility with the new version
Caveat Newer Java versions may introduce breaking API changes or deprecate features; test applications thoroughly before production deployment
