MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The ORDS Mongoapi component must be enabled and the ORDS instance must be reachable over HTTPS from the attacker's network position. The CVSS vector PR:N/AC:L/UI:N confirms no authentication, no special configuration complexity, and no user interaction are required. Exploitation is limited to deployments running ORDS versions 24.2.0 through 26.1.0 with the Mongoapi component active - organizations that have never configured or enabled Mongoapi are not exposed. Impact is bounded to reading a subset of data accessible via Mongoapi; no write, delete, or service disruption capability is indicated by the CVSS (I:N/A:N), which limits blast radius compared to higher-severity Oracle CPU findings. |
| Impact | The CVSS 3.1 base score of 5.3 (Medium) with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N presents a clear and consistent picture: network-reachable, no authentication required, trivially exploitable, but impact is limited strictly to partial confidentiality loss with no integrity or availability consequences. The 'Easily exploitable' language in the Oracle advisory reinforces the low-complexity rating. No EPSS score is available in the provided data, so automated exploitation probability cannot be quantified. The absence of KEV listing and no identified POC suggests opportunistic mass exploitation has not occurred as of the advisory date, though the zero-authentication, network-accessible nature means exploitation requires minimal sophistication. The practical risk is elevated for organizations that expose ORDS externally or to untrusted networks, particularly where the Mongoapi component is in active use and data sensitivity is high. The scope is limited (S:U), meaning a successful attacker cannot leverage this to pivot beyond the ORDS service boundary. |
| Exploit ScenarioDerived | An unauthenticated attacker with HTTPS network access to an exposed ORDS instance sends crafted requests to the Mongoapi endpoint, exploiting the authentication bypass to enumerate and read data accessible through that interface without presenting any credentials. Because attack complexity is low and no user interaction is required, this scenario is feasible with minimal tooling - a simple HTTP client or MongoDB-compatible driver pointed at the vulnerable endpoint suffices. No public proof-of-concept code has been identified at time of analysis, but the simplicity of the vector means independent rediscovery is plausible. |

Alert meAnalysisAIv1 – May 28, 2026
Unauthorized read access in Oracle REST Data Services (ORDS) versions 24.2.0 through 26.1.0 is achievable by unauthenticated remote attackers via the Mongoapi component over HTTPS. The vulnerability is tagged as an Authentication Bypass, indicating the Mongoapi endpoint fails to enforce access controls, exposing a subset of data accessible through that interface. No public exploit code and no CISA KEV listing exist at time of analysis, but the CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms low-complexity, zero-authentication exploitation is feasible at scale.
RemediationAI
Apply the patches distributed as part of Oracle's Critical Patch Update for May 2026, available at https://www.oracle.com/security-alerts/cspumay2026.html. The advisory does not specify an exact fixed version number in the data available for this analysis - the precise target upgrade version must be confirmed from the Oracle advisory or Oracle Support directly. As an immediate compensating control, organizations should restrict network access to the ORDS Mongoapi endpoint using firewall rules or network segmentation to limit exposure to trusted clients only, noting this does not remediate the authentication bypass but reduces the attack surface. If the Mongoapi component is not operationally required, disabling it entirely removes the attack surface with no functional impact to standard ORDS REST API usage. Organizations should also audit ORDS access logs for anomalous unauthenticated HTTPS requests to Mongoapi paths as a detection measure.

Technical ContextAI · show details
Oracle REST Data Services (ORDS) is Oracle's middleware layer that exposes Oracle Database content via RESTful APIs. The affected component, Mongoapi, provides a MongoDB-compatible API interface on top of Oracle Database, allowing clients that speak the MongoDB wire protocol or REST conventions to interact with Oracle data. The CPE string cpe:2.3:a:oracle_corporation:oracle_rest_data_services:*:*:*:*:*:*:*:* confirms Oracle Corporation as the vendor and ORDS as the product. The CWE is not formally assigned in available data, but the 'Authentication Bypass' tag strongly suggests the Mongoapi endpoint lacks proper authentication enforcement - meaning requests that should require credentials are processed without validating identity. The attack surface is the HTTPS-accessible Mongoapi endpoint, making any internet- or network-exposed ORDS deployment within the affected version range potentially vulnerable.
