CVE-2026-35320

Remote Code Execution via Unauthenticated HTTP Attack on Oracle WebCenter Content

Published Jun 16, 2026 CVSS 3.1 · 9 Critical 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. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Content. While the vulnerability is in Oracle WebCenter Content, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Content. 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

An unauthenticated attacker with network access via HTTP can exploit a flaw in the Content Server component of Oracle WebCenter Content. The vulnerability allows the attacker to execute arbitrary code, potentially taking full control of the application. Successful exploitation compromises confidentiality, integrity, and availability of the affected instance, resulting in a complete takeover.

Affected Systems

Oracle WebCenter Content 12.2.1.4.0 and 14.1.2.0.0 are vulnerable. The flaw’s scope change may affect other Oracle products that interact with WebCenter Content, but the primary targets remain the listed releases.

Risk and Exploitability

The CVSS v3.1 base score of 9.0 categorizes this as Critical, with no authentication, high complexity, no user interaction, and changed scope. The EPSS score of less than 1% indicates a low current exploitation probability, but the severity remains high. Because the vulnerability is reached over HTTP, it can be triggered remotely from any location that can contact the WebCenter Content service. The weakness involves incorrect permission evaluation (CWE-284), enabling the attacker to bypass access controls and execute code.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
