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 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 update, insert or delete access to some of Oracle REST Data Services accessible data. CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/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

Vulnerability in Oracle REST Data Services (ORDS) allows unauthenticated attackers with network access via HTTPS to perform unauthorized update, insert or delete operations on accessible data. The flaw is in the Core component and affects versions 24.2.0-26.1.0. Exploitation requires no authentication or user interaction, with low integrity impact but no confidentiality or availability impact.

MitigationApply Oracle's security patch for this vulnerability when released. Until then, restrict network access to ORDS endpoints to trusted sources only and monitor for unauthorized data manipulation attempts.

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 if ORDS is installed
    Check for ORDS installation by looking for the ords.war file, ORDS installation directory, or running processes containing 'ords' in the name. Common paths include $ORACLE_HOME/ords/ or /opt/ords/.
    Affected if ORDS software is found running or installed on the system
  2. Determine installed ORDS version
    Run 'java -jar ords.war version' or check the ords.war file version in the installation directory, or query the /ords/metadata-catalog endpoint if accessible.
    Affected if The version is >= 24.2.0 and <= 26.1.0
  3. Verify ORDS is exposed on network
    Check if ORDS HTTP/HTTPS listener ports (typically 8080, 8443, or custom ports) are bound to network interfaces accessible from outside localhost. Review firewall rules and reverse proxy configurations.
    Affected if ORDS endpoints are reachable from network addresses beyond localhost
  4. Confirm ORDS handles data operations
    Review ORDS configuration files (defaults.xml, ords.conf) and check which database connections ORDS is configured to access. Identify if the connected databases contain sensitive or valuable data.
    Affected if ORDS is configured to connect to databases or data sources
  5. Check for unauthenticated endpoints
    Review ORDS configuration for RESTful services or AutoREST enabled schemas that accept unauthenticated write operations. Check /ords/ endpoint accessibility without authentication.
    Affected if Unauthenticated write operations (INSERT, UPDATE, DELETE) are possible through ORDS endpoints

The environment is affected if ORDS versions 24.2.0 through 26.1.0 are installed and accessible over the network with any database connections configured.
