CVE-2026-46845

Oracle WebCenter Portal Unauthenticated Remote Code Execution via Improper Authorization

Published Jun 16, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Security Framework). 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 HTTPS to compromise Oracle WebCenter Portal. Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Portal. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Analysis

Technical impact

Oracle WebCenter Portal is vulnerable through its Security Framework component, permitting an attacker who can reach HTTPS services to gain unauthorized control over the entire portal. The flaw exposes the portal to complete takeover, impacting confidentiality, integrity, and availability. The vulnerability is categorized as an improper access control and authentication weakness that allows remote code execution for an unauthenticated attacker.

Affected Systems

Affected versions are Oracle WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0, part of Oracle Fusion Middleware. Any installation of these releases that exposes HTTPS endpoints to the network is susceptible.

Risk and Exploitability

The CVSS 3.1 base score of 9.8 indicates critical severity, and the vector shows network-based low complexity with no authentication or user interaction required. The EPSS score of less than 1% suggests low current exploitation probability, but the vulnerability is not listed in the CISA KEV catalog. Nonetheless, given the potential for system takeover, the risk remains high and the vulnerability is highly exploitable if an attacker can reach the portal over HTTPS.
