Vulnerability Assessment
| Exploitation Conditions | Exploitation requires the attacker to already hold high privileges on the Oracle REST Data Services instance (PR:H) and to reach it over the network via HTTP. Crucially, a successful attack also requires human interaction from a person other than the attacker (UI:R) - a separate victim must be induced to act - and the condition is difficult to win (AC:H), implying a race condition, timing dependency, or non-deterministic precondition rather than a simple request. These combined requirements (prior high privilege plus a second human participant plus high complexity) sharply limit realistic exploitation; impact is further bounded to partial read and partial update/insert/delete access to only a subset of ORDS-accessible data, with no availability impact. Applies to ORDS Core in supported versions 24.2.0 through 26.1.0. |
| Impact | This is a genuinely low-priority issue despite being network-reachable. The CVSS 3.1 base score of 3.1 (Low) is corroborated across every available signal rather than contradicted by them. The vector (AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N) shows that although the attack vector is network/HTTP, exploitation is gated by three independent mitigating factors simultaneously: high attack complexity (AC:H), the need for pre-existing high privileges (PR:H), and required interaction from a victim other than the attacker (UI:R). The impact is likewise limited - only partial (Low) confidentiality and integrity impact, no availability impact, and no scope change. No EPSS score, CISA KEV listing, or public proof-of-concept was supplied in the input, so there is no public exploit identified at time of analysis. There is no signal conflict to reconcile: a high-privileged, high-complexity, user-interaction-dependent flaw with only partial C/I impact is a low real-world risk, not a high-CVSS-but-overrated case. One data caveat: the input Tags include 'Authentication Bypass,' which directly contradicts the PR:H requirement in both the Oracle description and the CVSS vector - treat that tag as suspect, as this vulnerability requires an already-authenticated high-privileged actor rather than bypassing authentication. |
| Exploit ScenarioDerived | An attacker who already holds high-privileged access to an Oracle REST Data Services instance crafts a malicious HTTP interaction and lures a separate privileged user into triggering it, exploiting a difficult-to-win condition to gain limited unauthorized read, update, insert, or delete access to a subset of ORDS-accessible data. No public exploit code is identified at time of analysis, and the high complexity plus required victim interaction make opportunistic exploitation unlikely. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle REST Data Services (ORDS) versions 24.2.0 through 26.1.0 contain a difficult-to-exploit flaw in the Core component that lets a network-positioned attacker who already holds high privileges on the ORDS instance, and who persuades a separate user to perform some interaction, obtain limited read and limited insert/update/delete access to a subset of ORDS-accessible data. There is no availability impact, and the combination of prior high privilege (PR:H), a second human participant (UI:R), and a high-complexity precondition (AC:H) makes successful exploitation unlikely and low-value. No public exploit code was identified at time of analysis and the issue is not in CISA KEV; Oracle addresses it through its October 2026 Critical Patch Update advisory.
RemediationAI
Apply the fix from Oracle's October 2026 Critical Patch Update, which is the vendor's designated remediation for ORDS 24.2.0 through 26.1.0 (https://www.oracle.com/security-alerts/cpuoct2026.html); the exact patched ORDS build number is not stated in the available data, so confirm the target release against that advisory before upgrading, and note that ORDS upgrades require a re-run of the configuration/migration step against each database. Because exploitation demands high privileges plus a victim's interaction, the highest-leverage compensating controls are authorization-side: audit and trim membership in privileged ORDS roles and REST-enabled database schemas so that few accounts can reach the vulnerable code path, accepting the operational cost of tighter change control. Restrict network access to the ORDS HTTP listener with a reverse proxy or firewall allowlist limited to known API consumers, which stops untrusted clients reaching Core but will break legitimate external integrations until they are enumerated. Disable unused REST modules, handlers, and ORDS-published schemas to shrink the reachable surface, at the cost of removing functionality some applications may silently depend on. Since UI:R requires a second person to act, reinforce guidance against following unsolicited links or approving unexpected ORDS-driven prompts, and monitor ORDS and database audit logs for anomalous privileged requests, alerting on unusual sequences from high-privilege accounts.

Technical ContextAI · show details
Oracle REST Data Services is a Java-based mid-tier that publishes RESTful endpoints over Oracle Database, running standalone on Jetty or deployed into containers such as WebLogic or Tomcat; the affected component is ORDS Core, the request-routing and data-access layer shared by all publication paths. Oracle did not assign a CWE, so the root-cause class is unclassified, but the assessed vector (AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N) points to a non-deterministic precondition - a race, timing dependency, or state assumption - that only a caller already holding a highly privileged ORDS role can reach, and that additionally requires a distinct human to trigger or approve an action. Scope is unchanged, so the defect stays inside the ORDS security authority rather than crossing into the host or database. Note that third-party tagging labels this 'Authentication Bypass', which conflicts with the PR:H element of the official vector; treat it as a post-authentication, high-privilege issue rather than a pre-auth bypass. No CPE data was supplied beyond the EUVD range 24.2.0 ≤ 26.1.0.

CVSS VectorNVD
DescriptionNVD
Vulnerability in Oracle REST Data Services (component: Core). Supported versions that are affected are 24.2.0-26.1.0. Difficult to exploit vulnerability allows high 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. 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 3.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N).
