Published Aug 18, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle Reports Developer product of Oracle Fusion Middleware (component: Security and Authentication). The supported version that is affected is 12.2.1.19.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Reports Developer. Successful attacks of this vulnerability can result in takeover of Oracle Reports Developer. 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

An unauthenticated attacker who can reach Oracle Reports Developer over TCP can exploit a flaw in the security and authentication component, bypassing normal login requirements. The vulnerability allows the attacker to execute arbitrary code on the target and ultimately take full control of the Reports Developer instance. The attack compromises confidentiality, integrity, and availability of the application and any data it exposes. The flaw is defined by CWE-284.

Affected Systems

Oracle Reports Developer 12.2.1.19.0 running as part of Oracle Fusion Middleware is affected. Users running this exact version of the product are at risk.

Risk and Exploitability

The CVSS v3.1 Base Score of 9.8 signals a critical risk scenario. Although the EPSS score is less than 1%, indicating a low overall exploitation probability across all systems, any exposed deployment remains an attractive target because the vulnerability is exploitable without initial credential or code injection. The flaw is not listed in the CISA KEV catalog, but the high CVSS score combined with the unauthenticated network access vector warrants urgent attention.
