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 the Oracle Coherence product of Oracle Fusion Middleware (component: Centralized Third Party Jars). The supported version that is affected is 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. While the vulnerability is in Oracle Coherence, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Coherence accessible data as well as unauthorized update, insert or delete access to some of Oracle Coherence accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/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 · moderate confidence

A critical unauthenticated HTTP vulnerability in Oracle Coherence's Centralized Third Party Jars component (v15.1.1.0.0) allows remote attackers to gain high confidentiality impact (full data access) and low integrity impact (partial data modification) via easily exploitable network attacks. The scope change indicates this flaw may affect additional products beyond Oracle Coherence itself.

MitigationApply the Oracle Critical Patch Update for CVE-2026-35305 or deploy the specific security fix for Oracle Coherence 15.1.1.0.0. If immediate patching is not feasible, restrict network access to Coherence HTTP endpoints using network segmentation or web application firewall rules.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Oracle Coherence installation
    Locate Coherence installation directories or check system inventory for Oracle Coherence software packages
    Affected if Oracle Coherence is installed on the system
  2. Determine Coherence version
    Run version detection command or check version files specific to Oracle Coherence installation (consult Oracle documentation for your installation method)
    Affected if The installed version is exactly 15.1.1.0.0
  3. Verify HTTP endpoint exposure
    Check network configuration, firewall rules, or load balancer settings to determine if Coherence HTTP ports are accessible from network
    Affected if Coherence HTTP endpoints are network-accessible
  4. Confirm Centralized Third Party Jars component is in use
    Review Coherence configuration files or component listings to determine if Centralized Third Party Jars feature is enabled
    Affected if Centralized Third Party Jars component is configured or active

You are affected if Oracle Coherence version 15.1.1.0.0 is installed and its HTTP endpoints are network-accessible, particularly with the Centralized Third Party Jars component enabled.
