Vulnerability Assessment
| Exploitation Conditions | Exploitation requires that an authorized human user (explicitly 'a person other than the attacker') be induced to interact with attacker-supplied content over HTTP - i.e., a social-engineering/user-interaction step (UI:R) is mandatory, not optional. The attack is also rated high-complexity (AC:H), meaning the attacker must overcome conditions outside their direct control (e.g., timing, specific state, or a race). No valid credentials are needed (PR:N, unauthenticated). The key limiting factors defenders should weigh: the hard dependency on tricking a legitimate user, the high-complexity barrier, and the fact that no availability impact occurs - but note the scope change means a successful attack can propagate impact to products beyond ORDS itself. Oracle's description does not name a specific non-default feature or configuration prerequisite, so this appears to apply to standard ORDS deployments in the affected version range. |
| Impact | This is a moderate-priority issue rather than an emergency, and the signals are internally consistent rather than conflicting. The CVSS 3.1 base score is 6.9 (Medium), and the vector (AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:H/A:N) tells a nuanced story: network-reachable and unauthenticated (PR:N), which raises concern, but gated by high attack complexity (AC:H) AND required user interaction (UI:R), both of which substantially dampen real-world exploitability. The scope change (S:C) is the most notable element - Oracle explicitly states attacks 'may significantly impact additional products,' so blast radius can exceed ORDS itself. Impact is partial confidentiality (C:L, read of a data subset) but high integrity (I:H, unauthorized create/delete/modify of critical data) with no availability impact (A:N). No EPSS score, CISA KEV listing, or public POC was provided in the intelligence set, so there is no evidence of active or imminent mass exploitation; absence of these is not proof of safety but does argue against treating this as a drop-everything item. Net: a genuine integrity/scope-change risk worth patching in a normal Oracle CPU cycle, but the AC:H + UI:R combination makes opportunistic, widespread exploitation unlikely. Note one metadata tension: the 'Authentication Bypass' tag is not clearly supported by the description, which reads more like a UI-interaction-driven, scope-crossing attack than a classic auth bypass - verify the mechanism against Oracle's advisory. |
| Exploit ScenarioDerived | An unauthenticated attacker crafts a malicious HTTP request or link targeting the ORDS Core component and lures a legitimate user (someone other than the attacker) into interacting with it. Because the flaw causes a scope change, successful exploitation lets the attacker perform unauthorized create/delete/modify operations on critical data and read a subset of ORDS-accessible data, potentially reaching additional connected products. No public exploit code was identified at time of analysis, and the high attack complexity means exploitation is non-trivial and not guaranteed to succeed. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle REST Data Services versions 24.2.0 through 26.1.0 expose an unauthenticated HTTP attack path in the Core component that, when a legitimate user is induced to interact with attacker-supplied content, can bypass authentication and permit unauthorized creation, deletion, or modification of critical data plus limited read access; the scope change means impact may extend to integrated products beyond ORDS itself. Exploitation is high-complexity and user-interaction-dependent (AC:H/UI:R), has no availability impact, and no public exploit identified at time of analysis.
RemediationAI
Apply the Oracle REST Data Services update referenced in Oracle's October 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpuoct2026.html); the provided data does not state an exact fixed version, so validate that the deployed ORDS release is at or above the CPU-fixed level for the 24.2.0-26.1.0 range. Patch status is patch available per vendor advisory, but the exact fix version is not specified. Until patched, restrict HTTP access to ORDS endpoints to trusted clients and networks, monitor for anomalous create/delete/modify operations and authentication events, and reduce the required user-interaction risk through user awareness and content filtering; these compensating controls lower exposure but do not remove the flaw. Because the vector is PR:N/UI:R, do not treat authentication as sufficient protection and enforce least privilege on database accounts used by ORDS.

Technical ContextAI · show details
Oracle REST Data Services (ORDS) is Java-based middleware that publishes RESTful endpoints for Oracle Database and is commonly deployed in a servlet container or standalone mode. The issue sits in ORDS Core and is reachable over HTTP with no credentials required (PR:N), but the CVSS vector requires a person other than the attacker to perform an interaction (UI:R) and rates attack complexity high (AC:H), so reliable exploitation depends on social engineering plus conditions outside the attacker's direct control. The scope change (S:C) means a compromise can affect products and trust boundaries beyond ORDS; impact is confidentiality-low and integrity-high with no availability effect. No CWE is provided, but the Authentication Bypass tag and the integrity-focused impact point to a flaw in authentication or authorization enforcement in ORDS Core; the specific non-default configuration prerequisite is not disclosed and none is identified in the supplied data.

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 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 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 read access to a subset of Oracle REST Data Services accessible data. CVSS 3.1 Base Score 6.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:H/A:N).
