CVE-2026-35308
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 · uneditedVulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Centralized Third Party Jars). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 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 takeover of Oracle Coherence. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
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 confidenceThis is a critical unauthenticated remote code execution vulnerability in Oracle Coherence's Centralized Third Party Jars component. An attacker with network access via HTTP can exploit this flaw to achieve complete takeover of the Oracle Coherence server, potentially impacting additional products in the environment due to scope change. The CVSS 10.0 score indicates trivial exploitability with no user interaction required.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Oracle Coherence versionCheck the Coherence installation directory for version files, or examine the coherence.jar manifest, or query the Coherence MBean via JMX/management interface for product versionAffected if Installed version matches 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0
-
Determine if Centralized Third Party Jars is enabledReview Coherence configuration files (coherence-cache-config.xml, tangosol-coherence.xml, or operational configuration) for the Centralized Third Party Jars feature or related classloader configurationAffected if Centralized Third Party Jars feature is configured or enabled in the Coherence configuration
-
Verify HTTP network exposure of Coherence endpointsScan network accessible ports and review firewall/load balancer rules to confirm HTTP-based Coherence REST endpoints, MBean over HTTP, or similar management interfaces are externally accessibleAffected if Coherence HTTP-based endpoints are reachable from untrusted network segments
You are affected if you have an affected Coherence version with Centralized Third Party Jars enabled and HTTP network access is exposed to the Coherence server.

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.
From vendor dataApply the Oracle Coherence patch for this vulnerability or upgrade to a patched version. If immediate patching is not possible, restrict network access to Coherence HTTP endpoints using network segmentation or a web application firewall.
