CVE-2026-83105

Unauthenticated Remote Code Execution via HTTP in Oracle Forms

Published Sep 15, 2026 CVSS 3.1 · 9 Critical EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle Forms product of Oracle Fusion Middleware (component: Forms Services, C/S, Charmode). Supported versions that are affected are 12.2.1.19.0 and 14.1.2.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Forms. While the vulnerability is in Oracle Forms, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Forms. CVSS 3.1 Base Score 9.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).

Analysis

Technical impact

Oracle Forms services in Oracle Fusion Middleware expose an unauthenticated HTTP interface that can be abused to execute arbitrary code on the host. The vulnerability is caused by improper access control (CWE-284), allowing an attacker to run code with the privileges of the Forms process. Successful exploitation would result in loss of confidentiality, integrity, and availability for the affected deployment, potentially impacting other Oracle components that rely on Forms Services, C/S, or Charmode.

Affected Systems

Oracle Forms versions 12.2.1.19.0 and 14.1.2.0.0, part of Oracle Fusion Middleware. The flaw applies to the Forms Services, C/S, and Charmode components, and may also affect additional Oracle products that depend on these services.

Risk and Exploitability

The CVSS score of 9.0 (AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H) marks this flaw as critical. The EPSS score of less than 1% indicates a low current exploitation probability, and the vulnerability is not listed in the CISA KEV catalog. Nevertheless the attack requires only unauthenticated HTTP access, and the high complexity coupled with a scope change means that a compromised Forms instance could grant an attacker full control over the affected system and possibly other Oracle components.

OpenCVE Recommended Actions

Apply the latest Oracle Forms patch for the affected versions as issued in Oracle’s security alerts.
If patching cannot be performed immediately, block unauthenticated HTTP traffic to the Forms services using firewall rules or network segmentation to reduce exposure.
Monitor web‑application logs for abnormal HTTP requests or signs of exploitation attempts and investigate any suspicious activity.
