MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the attacker to already hold a low-privileged account on Oracle REST Data Services (PR:L) and to reach the ADP component over HTTP (AV:N). Successful attack additionally REQUIRES human interaction from a different person (UI:R) - a victim must view or act on attacker-supplied content - so it cannot be triggered unattended. The scope change (S:C) means impact can extend to additional products beyond ORDS. Limiting factors: valid authentication, mandatory third-party user interaction, and the affected version window 24.2.0-26.1.0; impact is partial (C:L/I:L) with no availability effect (A:N). |
| Impact | This is a medium-severity, authenticated, user-interaction-dependent vulnerability that should be treated as a routine-to-moderate patch priority rather than an emergency. The Oracle-supplied CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, base 5.4) describes a low-privileged attacker over HTTP who needs a separate victim to interact, yielding partial confidentiality and integrity impact with a scope change to other products - a profile strongly consistent with a stored/reflected cross-site scripting or injection issue, NOT the 'Authentication Bypass' implied by the input tag (see data_quality_flags). No EPSS score was provided in the input, there is no CISA KEV listing, and no public exploit code is referenced, so there is no evidence of exploitation pressure - no public exploit identified at time of analysis. The requirement for both valid low-level privileges (PR:L) and human interaction from a third party (UI:R) materially lowers real-world risk versus the raw network attack vector, since an attacker cannot act fully unauthenticated or unattended. Net: a genuine but non-critical issue - apply the October 2026 Oracle CPU fix on a normal cycle; the absence of availability impact (A:N) and lack of full system compromise argue against treating it as a drop-everything item. |
| Exploit ScenarioDerived | An attacker holding a low-privileged Oracle REST Data Services account submits crafted input (e.g., a malicious payload stored or reflected through the ADP component) and lures a higher-value user into viewing it over HTTP. When that victim interacts with the content, the payload executes in their context, allowing limited unauthorized read of some data and unauthorized insert/update/delete of other data, with effects crossing into additional connected products due to the scope change. No public exploit code is identified at time of analysis. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle REST Data Services (ORDS) versions 24.2.0 through 26.1.0 contain an ADP-component security flaw that is tagged Authentication Bypass but, per the assessed vector, requires a low-privileged authenticated attacker and a separate user's interaction over HTTP. Successful exploitation can read and modify a limited subset of ORDS-accessible data, and the scope change means affected downstream products may also be impacted; there is no availability impact. CVSS 3.1 is 5.4 (medium), and no public exploit has been identified at time of analysis.
RemediationAI
Apply the Oracle Critical Patch Update referenced in the vendor advisory (https://www.oracle.com/security-alerts/cpuoct2026.html) to move ORDS outside the 24.2.0-26.1.0 affected range; the input does not state an exact fixed version, so confirm the target release in the advisory. Until patched, restrict HTTP access to the ADP component to trusted networks or users, remove unnecessary low-privileged ORDS accounts, and warn users not to act on unsolicited content because UI:R is required; these measures lower exposure but can break legitimate integrations and do not substitute for the vendor fix.

Technical ContextAI · show details
The CVE affects the ADP component of Oracle REST Data Services, a REST/HTTP interface to Oracle Database data. No CWE is supplied, so the precise root-cause class is not confirmed; the Authentication Bypass tag should not be read as permitting unauthenticated access because the CVSS vector is PR:L. The vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N means an attacker with a low-privileged account can reach the component over the network, but a different person must first interact with attacker-influenced content; the S:C scope change indicates impact can cross into additional products, while C:L/I:L and A:N cap the effect to partial confidentiality/integrity loss with no availability impact. EUVD confirms the affected range as 24.2.0 ≤26.1.0; no CPE strings were provided.

DescriptionCVE.org
Vulnerability in Oracle REST Data Services (component: ADP). Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP 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 update, insert or delete access to some of Oracle REST Data Services accessible data as well as unauthorized read access to a subset of Oracle REST Data Services accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).
