CVE-2026-35266
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. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTPS to compromise Oracle REST Data Services. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle REST Data Services, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle REST Data Services accessible data as well as unauthorized access to critical data or complete access to all Oracle REST Data Services accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle REST Data Services. CVSS 3.1 Base Score 7.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/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 · high confidenceOracle REST Data Services (ORDS) Core component contains a vulnerability in versions 24.2.0-26.1.0 that allows low-privileged attackers with network access via HTTPS to potentially create, modify, or delete critical data, access all ORDS data, or cause partial denial of service. The attack requires human interaction and results in scope change affecting additional products.

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 ORDS installation and versionLocate the ORDS installation directory or ords.war file and determine the installed version number (typically found in the war file metadata, version file, or via the /ords/_/health endpoint)Affected if The installed version falls within the range >= 24.2.0 and <= 26.1.0
-
Verify ORDS is accessible over networkCheck network configuration, firewall rules, or load balancer settings to determine if ORDS HTTPS endpoints are exposed to network access beyond trusted internal networksAffected if ORDS HTTPS endpoints are reachable from untrusted networks or the internet
-
Confirm authentication is enforced on ORDSInspect ORDS configuration files (including ords.conf, wallet settings, and security constraints) to verify that authentication is required for access to ORDS endpointsAffected if ORDS endpoints allow unauthenticated or anonymous access, or authentication can be bypassed
-
Check for suspicious ORDS activityReview ORDS access logs for unusual patterns such as unexpected API calls, privilege escalation attempts, or anomalous data access from low-privileged accountsAffected if Logs show unexpected activity from low-privileged users performing privileged operations or accessing data outside their normal scope
The environment is affected if ORDS version 24.2.0 through 26.1.0 is installed and network-accessible, regardless of authentication status, since the vulnerability requires only low-privileged access and human interaction to exploit.

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 Oracle's patched version of Oracle REST Data Services (ORDS) when available. Until then, restrict network access to ORDS endpoints, enforce strict authentication, and monitor for suspicious user activities.
