Vulnerability Assessment
| Exploitation Conditions | Exploitation requires human interaction from a person other than the attacker (CVSS UI:R) - a legitimate ORDS user must be induced to interact with attacker-crafted input/link, so this cannot be driven to completion by the attacker alone and is amenable to phishing/social-engineering defenses. The affected component is specifically ORDS Backend-as-a-Service, reachable over HTTP, in versions 24.2.0 through 26.1.0; environments not exposing this component or already patched per the Oracle October 2026 CPU are not affected. No authentication is required of the attacker (PR:N), and impact is limited to a subset of ORDS-accessible data with partial read and partial update/insert/delete, no availability effect. |
| Impact | This is a moderate-severity issue (CVSS 3.1 base 5.4) that does NOT rise to a drop-everything priority. The vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N shows network reachability and no attacker privileges, but mandatory user interaction (UI:R) and only LOW confidentiality and integrity impact with NO availability impact - meaning an attacker cannot act alone and gains only partial read plus partial update/insert/delete on a subset of ORDS-accessible data. No EPSS score was provided in the input, so exploitation probability cannot be quantified. The CVE is not listed in CISA KEV and no public exploit is identified, so there is no evidence of active exploitation; this is a vendor-reported (secalert_us@oracle.com) flaw disclosed via the Oracle October 2026 CPU rather than a signal of in-the-wild abuse. The CVSS network vector is consistent with the description's 'network access via HTTP.' One tension to verify: the input Tag labels this 'Authentication Bypass,' yet the description describes unauthenticated-but-user-interaction-dependent unauthorized data access with partial C/I impact - a pattern more typical of CSRF or reflected injection than a true auth bypass; treat the tag as unconfirmed. Overall: a real but second-tier item best handled via normal Oracle CPU patch cycles unless ORDS Backend-as-a-Service is internet-exposed. |
| Exploit ScenarioDerived | An attacker crafts a malicious HTTP link or page targeting an ORDS Backend-as-a-Service endpoint and lures a legitimate user (e.g. via phishing) into visiting it. When the victim interacts, the request executes in their context, letting the attacker read a subset of ORDS-accessible data and perform some unauthorized insert/update/delete operations. No public exploit code is identified at time of analysis, and the required human interaction raises the practical bar. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle REST Data Services versions 24.2.0 through 26.1.0 expose an access-control weakness in the Backend-as-a-Service component that lets an unauthenticated network attacker over HTTP obtain partial read and partial insert/update/delete access to ORDS-accessible data, scored CVSS 3.1 base 5.4 (C:L/I:L/A:N). Exploitation is not attacker-completable on its own: the vector carries UI:R, so a legitimate ORDS user must be induced into a crafted interaction, making phishing and social-engineering defenses directly relevant. No public exploit code or CISA KEV entry was identified at time of analysis, and Oracle addresses the flaw in its October 2026 Critical Patch Update; this is a moderate-severity item rather than a drop-everything priority.
RemediationAI
Patch available per vendor advisory: apply the Oracle October 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpuoct2026.html), which covers the affected 24.2.0-26.1.0 range; the supplied data does not name a specific fixed build, so confirm the target version against the CPU matrix before closing the finding. Because exploitation requires victim interaction (UI:R), pair patching with anti-phishing and browser-side controls, and consider shortening or partitioning user sessions on ORDS BaaS endpoints - the trade-off is added friction for legitimate API and UI consumers. Where patching must wait, restrict the BaaS HTTP endpoints to trusted networks or front them with a reverse proxy that enforces origin/CSRF protections and allowlists, accepting that third-party and mobile integrations may break; and reduce blast radius by running ORDS against a least-privilege database account with no DDL or cross-schema grants, which limits the partial read/write impact but may require reworking existing service definitions. Monitor ORDS access logs and database audit trails for anomalous requests tied to authenticated user sessions, since the attacker's own traffic will look unauthenticated and unremarkable.

Technical ContextAI · show details
Oracle REST Data Services (ORDS) is a Java-based mid-tier that publishes RESTful HTTP endpoints over Oracle Database schemas, and the affected Backend-as-a-Service component is the layer that brokers those service definitions and data operations to clients. No CWE was published with this CVE, but the accompanying 'Authentication Bypass' tag combined with a PR:N/UI:R profile is consistent with an access-control/authorization weakness that is reached through a victim's already-established browser or client session rather than through a directly authenticated attacker request - i.e., a confused-deputy or cross-site request pattern where the attacker supplies crafted input and the victim's interaction supplies the missing authorization context. Impact is bounded to a subset of ORDS-accessible data with partial confidentiality and partial integrity effects and no availability impact (S:U, A:N), so the blast radius is determined by the privileges of the database schema behind the exposed BaaS endpoints. EUVD independently confirms the affected range as ORDS 24.2.0 ≤ 26.1.0; no CPE strings were supplied in the source data, so exact platform/build enumeration should be taken from the Oracle CPU matrix.

CVSS VectorNVD
DescriptionNVD
Vulnerability in Oracle REST Data Services (component: Backend-as-a-Service). Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows unauthenticated 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 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N).
