Oracle Product Workbench within the Oracle E-Business Suite contains a critical vulnerability that permits unauthenticated attackers to compromise the system. The flaw, identified as CVE-2026-101808, enables remote exploitation via HTTP without requiring any user credentials. This issue poses a severe risk to organizations using supported versions of the software.

The National Vulnerability Database rates the flaw with a CVSS 3.1 Base Score of 9.1, classifying it as critical. The vulnerability is easily exploitable by an attacker with network access. Successful exploitation allows for unauthorized creation, deletion, or modification of critical data. Attackers can also gain complete access to all accessible data within the Oracle Product Workbench component.

Technical Severity and Impact Scope

The CVSS vector indicates that the attack vector is network-based with low complexity. No privileges or user interaction are required to exploit the vulnerability. The scope remains unchanged, but both confidentiality and integrity suffer high impacts. The availability impact is rated as none. This combination results in the maximum critical severity rating.

According to the NVD record, the weakness affects the WebUI component of Oracle Product Workbench. The vulnerability allows for unauthorized access to critical data. It also permits complete access to all data accessible through the Oracle Product Workbench interface. The lack of authentication requirements significantly lowers the barrier for potential attackers.

Affected Oracle E-Business Suite Versions

The vulnerability impacts a wide range of Oracle E-Business Suite versions. Specifically, versions 12.2.3 through 12.2.15 are affected by this security flaw. Organizations running any of these supported versions are exposed to the risk. The broad version range suggests many deployments may be vulnerable.

Oracle Product Workbench is the specific product within the suite that contains the defect. The WebUI component is the entry point for the attack. Users of these versions should verify their current installation status. The NVD record confirms these are the only supported versions currently identified as affected by CVE-2026-101808.

What should you do?

Organizations should immediately inventory their Oracle E-Business Suite installations to determine if they run versions 12.2.3 through 12.2.15. Network access controls should be reviewed to restrict HTTP traffic to the WebUI component. Monitoring for unauthorized access attempts is essential until a fix is confirmed.

What to do and how to stay safe: Oracle

Inventory all Oracle E-Business Suite installations to identify versions 12.2.3 through 12.2.15.
Restrict network access to the Oracle Product Workbench WebUI component via HTTP.
Monitor logs for unauthorized access attempts or data modification activities.
Await official vendor guidance or patches for CVE-2026-101808 before assuming resolution.
