Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 20 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Apply official Oracle patches as soon as they become available for versions 12.2.3 through 12.2.15 of Oracle Configurator. 2. Restrict network access to Oracle Configurator interfaces by implementing network segmentation and firewall rules to limit HTTP access only to trusted internal users and systems. 3. Employ web application firewalls (WAFs) to detect and block suspicious HTTP requests targeting Oracle Configurator endpoints. 4. Conduct regular monitoring and logging of access to Oracle Configurator, focusing on unusual or unauthorized read attempts. 5. Review and harden Oracle E-Business Suite configurations to minimize exposed data and disable unnecessary services or interfaces. 6. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling. 7. Consider deploying intrusion detection systems (IDS) with signatures tuned to detect exploitation attempts against Oracle Configurator. 8. If feasible, temporarily disable or isolate Oracle Configurator components exposed to untrusted networks until patches are applied. 9. Coordinate with Oracle support for guidance and early access to patches or workarounds. 10. Perform vulnerability scanning and penetration testing focused on Oracle Configurator to identify exposure and validate mitigations.

Description

Vulnerability in the Oracle Configurator product of Oracle E-Business Suite (component: User Interface). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Configurator. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Configurator accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

Impact

For European organizations, the primary impact is unauthorized disclosure of sensitive configuration data managed by Oracle Configurator. This could lead to exposure of proprietary product configurations, business process details, or customer-related information, potentially resulting in competitive disadvantage or compliance violations under regulations like GDPR. Although the vulnerability does not allow modification or disruption of services, the confidentiality breach alone can have significant business repercussions. Organizations in sectors such as manufacturing, telecommunications, and finance that rely heavily on Oracle E-Business Suite for product configuration and order management are particularly at risk. The ease of exploitation without authentication increases the threat level, especially if Oracle Configurator interfaces are exposed to untrusted networks or the internet. The absence of known exploits in the wild suggests limited active exploitation currently, but the vulnerability’s characteristics warrant proactive defense. Additionally, the medium severity score indicates that while the impact is not critical, it is substantial enough to require timely remediation to prevent data leakage and potential follow-on attacks leveraging exposed information.
