CVE-2026-83488

Published Sep 15, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed

Description

Vulnerability in the Helidon product of Oracle Fusion Middleware (component: helidon-microprofile-security). Supported versions that are affected are 4.0.0-4.5.4. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Helidon. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Helidon accessible data as well as unauthorized read access to a subset of Helidon accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N).

Analysis

Technical impact

The vulnerability in Helidon MicroProfile Security allows a low‑privileged attacker with network access via HTTP to perform unauthorized updates, inserts, or deletes on data exposed by Helidon, and to read a subset of that data. The flaw arises from improper authorization controls in the Helidon MicroProfile Security component, leading to confidentiality and integrity impacts as reflected in the CVSS vector. Availability remains unaffected.

Affected Systems

Oracle Helidon versions 4.0.0 through 4.5.4 are affected. These are part of Oracle Fusion Middleware and are deployed in environments that expose HTTP endpoints for Helidon services.

Risk and Exploitability

The CVSS base score of 5.4 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N) indicates moderate risk. The EPSS score of less than 1% signals a low probability of exploitation in the wild, and the vulnerability is not listed in the CISA KEV catalog. Attackers only need network connectivity to a Helidon HTTP interface; no local privilege or user interaction is required beyond a low privileged user context. The exploit is considered easily exploitable based on vendor characterization.
