CVE-2026-83244

Local Network Exploit Enables Unauthorized Access and Denial of Service in Oracle Commerce Guided Search

Published Sep 15, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Forge). The supported version that is affected is 11.4.0. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Commerce Guided Search / Oracle Commerce Experience Manager executes to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data as well as unauthorized update, insert or delete access to some of Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Commerce Guided Search / Oracle Commerce Experience Manager. CVSS 3.1 Base Score 7.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:H).

Analysis

AI-generated

Technical impact

A flaw in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager component “Forge” enables an attacker to gain unauthorized access to application data and to exploit configuration flaws that allow data alteration or deletion. Successful exploitation can lead to the disclosure of confidential information, the tampering of searchable content, or the triggering of application hangs and crashes, causing a complete denial of service to legitimate users.

Affected Systems

Oracle Corporation’s Oracle Commerce Guided Search / Oracle Commerce Experience Manager version 11.4.0 is known to be vulnerable. No other versions or editions appear to be affected at this time.

Risk and Exploitability

The vulnerability requires the attacker to be connected to the same physical communication segment as the server hosting the component, indicating a local‑segment attack vector; this inference is made because the description specifies "unauthenticated attacker with access to the physical communication segment." The EPSS score is below 1%, suggesting a low probability of exploitation in the wild, and the flaw is not listed in the CISA KEV catalog. Nevertheless, the CVSS base score of 7.1, coupled with the potential for both confidentiality and availability compromise, demands that the flaw be treated as a moderate‑to‑high priority. Defenses should focus on preventing local network access and monitoring for signs of unauthorized activity.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor-issued patch or upgrade for Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0 to a version that contains the fix.
  • Limit physical network access to the server by enforcing NIC‑level isolation, VLAN segmentation, or firewall rules that block unauthorized inbound traffic on the host’s network interface.
  • Continuously monitor application logs for anomalous authentication, modification, or crash events and configure alerts to detect attempted exploitation attempts.
