Unauthenticated HTTP Vulnerability Enabling Data Modification and Partial Denial of Service in Oracle WebCenter Content

Published Oct 20, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
Vulnerability in the Oracle WebCenter Content product of Oracle Fusion Middleware (component: Content Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Content. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebCenter Content accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle WebCenter Content. CVSS 3.1 Base Score 5.4 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L).

Analysis

AI-generated

Technical impact

The flaw is an authentication bypass in the Content Server component of Oracle WebCenter Content, inferred from the description that an unauthenticated attacker with network access over HTTP can gain update, insert, or delete rights on protected data and cause a partial denial of service. Because the vulnerability does not affect confidentiality, the primary impacts are integrity and availability, as reflected in the CVSS v3.1 base score of 5.4.

Affected Systems

Oracle WebCenter Content versions 12.2.1.4.0 and 14.1.2.0.0 are affected. These releases are part of Oracle Fusion Middleware and provide enterprise content management functions.

Risk and Exploitability

The CVSS score of 5.4 places the risk in the medium category. An EPSS score of less than 1% indicates a very low probability of remote execution in the wild, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires no local credentials but does need the victim to be prompted to interact with the system; the attacker must have HTTP access to the exposed Content Server interface. The combination of a moderate CVSS score, low exploitation probability, and the requirement for user interaction suggests that organizations should prioritize timely patching but may also monitor user activity for suspicious interactions.

Remediation

No solution or workaround provided in the CVE record.
