CVE-2026-83308

Low-Privilege SOAP Interface Vulnerability Enables Unauthorized Data Manipulation and Denial of Service

Published Sep 15, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle BI Publisher product of Oracle Analytics (component: BI Platform Security). Supported versions that are affected are 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via SOAP to compromise Oracle BI Publisher. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle BI Publisher accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle BI Publisher. CVSS 3.1 Base Score 8.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).

Analysis

Technical impact

Oracle BI Publisher’s SOAP interface exposes a flaw that allows a low‑privileged attacker with network access to create, delete or modify critical data and to trigger complete application hangs or crashes. The vulnerability is identified in the BI Platform Security component and occurs when SOAP requests bypass sufficient access controls. The impact is direct loss of data integrity and application availability, potentially affecting all data exposed through Oracle BI Publisher.

Affected Systems

Oracle BI Publisher versions 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0 are affected. Any deployment that has the SOAP API exposed to external networks is susceptible to these attacks.

Risk and Exploitability

The CVSS 3.1 base score of 8.1 reflects severe integrity and availability consequences. The EPSS score of <1% indicates a very low probability of exploitation in the current threat environment, but the vulnerability is not listed in CISA’s KEV catalog, so the potential business impact remains significant. The likely attack vector is over the network via crafted SOAP requests; the description suggests that low‑privilege credentials or even no authentication are sufficient, although this is inferred rather than explicitly documented.

OpenCVE Recommended Actions

Upgrade Oracle BI Publisher to the latest patched release to eliminate the known vulnerability.
Restrict network access to the SOAP API by configuring firewalls or VPNs so that only trusted hosts can reach the service.
Enforce strict authentication and authorization on the SOAP interface, ensuring that low‑privileged users cannot invoke data‑modifying operations.
