HIGH 8.6

DescriptionCVE.org

Vulnerability in the Oracle WebCenter Sites product of Oracle Fusion Middleware (component: WebCenter Sites). 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 Sites. While the vulnerability is in Oracle WebCenter Sites, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Sites accessible data. CVSS 3.1 Base Score 8.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

AnalysisAI

Unauthorized data disclosure in Oracle WebCenter Sites 12.2.1.4.0 and 14.1.2.0.0 lets a remote, unauthenticated attacker reach and read all data accessible to the application over HTTP, with a scope change that can significantly impact other connected products. The flaw is tagged as an authentication bypass and carries a CVSS 3.1 score of 8.6 driven entirely by confidentiality impact. No public exploit is identified at time of analysis, and it is fixed in the Oracle Critical Patch Update of July 2026.

Technical ContextAI

Oracle WebCenter Sites is an enterprise web experience management (WEM/WCM) platform within Oracle Fusion Middleware, typically deployed on WebLogic Server to author and deliver content-driven websites. The vulnerability sits in the WebCenter Sites component itself and, per the vendor, is characterized as an authentication bypass reachable directly over HTTP without credentials. Oracle assigned no CWE (CWE: N/A), but the combination of pre-authentication access plus a CVSS scope change (S:C) indicates the WebCenter Sites security boundary can be crossed to reach data and resources belonging to other components/products beyond the vulnerable module. The impact is confined to confidentiality (C:H, with I:N/A:N), meaning attackers can read data but the flaw does not itself grant modification or denial of service.

RemediationAI

Apply the fixes delivered in the Oracle Critical Patch Update of July 2026 (Patch available per vendor advisory) documented at https://www.oracle.com/security-alerts/cpujul2026.html; Oracle CPU patches are cumulative, so install the corresponding WebCenter Sites patch for your 12.2.1.4.0 or 14.1.2.0.0 deployment as the primary remediation. The input does not include a discrete standalone fix version beyond the CPU, so treat the July 2026 CPU bundle as the authoritative patch reference. As compensating controls until patching, restrict network reachability of the WebCenter Sites HTTP interface to trusted management networks or place it behind a VPN, and add a WAF/reverse-proxy rule to limit and inspect unauthenticated HTTP access to administrative and content-delivery endpoints - noting these controls reduce exposure but do not close an authentication bypass and may block legitimate anonymous content delivery if the site serves public traffic.
