CVE-2026-46843
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 Oracle REST Data Services (component: Core). Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle REST Data Services. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle REST Data Services. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
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 confidenceOracle REST Data Services (ORDS) versions 24.2.0 through 26.1.0 contain a vulnerability in the Core component that allows unauthenticated remote attackers to cause a partial denial of service via network requests over HTTPS. The attack requires no authentication or user interaction, and exploits the availability impact vector with low complexity.

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 Oracle REST Data Services installationLocate the ORDS installation directory and identify the version file or startup script that contains the version number. Common locations include the ORDS home directory, war file manifest, or the configuration directory.Affected if ORDS is found and running in the environment
-
Determine installed ORDS versionCheck the version of Oracle REST Data Services by examining the war file manifest, version.txt file, or running 'java -jar ords.war version' if applicable. Compare this version against the affected range of 24.2.0 through 26.1.0.Affected if Installed version is 24.2.0, 24.3.0, 24.4.0, 25.0.0, 25.1.0, 26.0.0, or 26.1.0
-
Verify HTTPS network exposureDetermine if the ORDS instance is exposed to network access via HTTPS. Check theORDS configuration for the HTTPS listener port and whether it is bound to a publicly accessible network interface.Affected if ORDS is listening on a reachable HTTPS port exposed to network traffic
-
Confirm unauthenticated access pathVerify that the ORDS endpoints are accessible without authentication. Check if the ORDS endpoints allow unauthenticated requests over the network.Affected if ORDS accepts unauthenticated HTTPS requests from network clients
A user is affected if Oracle REST Data Services is running with a version between 24.2.0 and 26.1.0 inclusive and is exposed to unauthenticated HTTPS network access.

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 or upgrade to ORDS version 26.2.0 or later to resolve this vulnerability. Since this is an unauthenticated DoS, consider implementing rate limiting or web application firewall rules as a temporary mitigation while planning the upgrade.
