CVE-2026-21946
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 JD Edwards EnterpriseOne Tools product of Oracle JD Edwards (component: Web Runtime SEC). Supported versions that are affected are 9.2.0.0-9.2.26.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise JD Edwards EnterpriseOne Tools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in JD Edwards EnterpriseOne Tools, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of JD Edwards EnterpriseOne Tools accessible data as well as unauthorized read access to a subset of JD Edwards EnterpriseOne Tools accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/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 confidenceA vulnerability in the Web Runtime SEC component of JD Edwards EnterpriseOne Tools (versions 9.2.0.0-9.2.26.0) allows unauthenticated attackers with network access via HTTP to compromise the system. Successful exploitation grants unauthorized read, insert, update, and delete access to a subset of accessible data, and may impact additional products due to scope change.

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 JD Edwards EnterpriseOne Tools versionLocate the Tools release information through the Oracle JD Edwards EnterpriseOne Deployment Guide, JDE Plan, or by querying the Server Manager. The version is typically found in the 'Release' or 'Tools Release' field.Affected if Installed version falls within 9.2.0.0 through 9.2.26.0 inclusive
-
Confirm Web Runtime SEC component is in useDetermine whether the Web Runtime (HTML Server) SEC component is deployed and actively serving requests. This component handles Web Runtime security functionality and is part of the HTML Server configuration.Affected if Web Runtime SEC component is enabled and processing HTTP requests
-
Verify HTTP accessibility of JD Edwards web interfacesCheck if the JD Edwards web interfaces (including the HTML Server endpoint) are reachable over HTTP or untrusted networks. Attempt to access the Web Runtime login or service endpoints from an untrusted network segment.Affected if Web Runtime endpoints are accessible via HTTP from untrusted or external networks without additional authentication barriers
-
Review network exposure of web servicesInspect firewall rules, network segmentation, and access control lists to determine if JD Edwards web interfaces are exposed to unauthenticated or untrusted network segments.Affected if Network allows unauthenticated HTTP access to JD Edwards web interfaces from outside the trusted network
A user is affected if their JD Edwards EnterpriseOne Tools version is between 9.2.0.0 and 9.2.26.0 AND the Web Runtime SEC component is accessible via HTTP from networks where attackers could reach the service without authentication.

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 patch for this vulnerability when available; until then, restrict network access to JD Edwards web interfaces and implement additional authentication layers such as web application firewall or VPN.
