CVE-2026-62618 in Reports Developer
Summary
by MITRE • 08/19/2026
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 HTTP to compromise Oracle Reports Developer. While the vulnerability is in Oracle Reports Developer, 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 Reports Developer accessible data as well as unauthorized update, insert or delete access to some of Oracle Reports Developer accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Oracle Reports Developer component of Oracle Fusion Middleware, specifically affecting version 12.2.1.19.0 and potentially other supported releases depending on configuration. This security flaw is classified under the Security and Authentication module, indicating a fundamental weakness in how the application verifies user identity or manages session states before granting access to sensitive resources. The nature of this vulnerability allows an unauthenticated attacker with network access via HTTP to exploit the defect remotely without requiring any prior authentication credentials or user interaction. This characteristic significantly lowers the barrier for exploitation, enabling automated attacks from remote locations over standard web protocols.
From a technical perspective, the flaw likely stems from insufficient validation of input parameters or improper enforcement of access control policies within the reporting engine's interface. When an attacker sends specially crafted HTTP requests to the Oracle Reports Developer service, the application fails to properly authenticate the requestor before processing sensitive operations. This lack of proper authorization checks allows malicious actors to bypass security boundaries that are designed to restrict data visibility and modification rights. The vulnerability is not isolated strictly to the reports module itself; due to the interconnected nature of enterprise middleware architectures, successful exploitation can lead to a scope change where additional products or underlying database systems become compromised.
The operational impact of this vulnerability is severe, as reflected by its CVSS 3.1 Base Score of 9.3, which denotes a Critical severity level. The primary impacts are on Confidentiality and Integrity, with Availability remaining unaffected according to the provided vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N). A successful attack results in unauthorized access to critical data stored within or accessible by Oracle Reports Developer. This includes sensitive business intelligence reports, financial records, and proprietary information that should be restricted to authorized personnel only. Furthermore, the vulnerability permits unauthorized update, insert, or delete operations on some of the accessible data. This integrity violation means attackers can alter existing records, inject false data into reporting databases, or permanently destroy valuable information, leading to significant operational disruption and potential regulatory compliance failures.
In terms of industry standard classifications, this vulnerability aligns with CWE-287 (Improper Authentication) as it allows unauthenticated access, and potentially CWE-862 (Missing Authorization) if the issue involves bypassing role-based controls after initial connection establishment. The attack vector corresponds to MITRE ATT&CK technique T1078 (Valid Accounts), although in this specific case, it applies to valid system accounts or services that are improperly exposed without requiring explicit user authentication steps for sensitive endpoints. It also relates to T1530 (Data from Cloud Storage) if the reports pull data directly from cloud-based repositories, and T1213 (Data from Information Repositories) given the nature of reporting tools accessing structured databases.
Mitigation strategies must focus on immediate remediation through vendor-provided patches or updates that address the authentication logic flaws within Oracle Reports Developer. Organizations should apply the latest security bundles released by Oracle for version 12.2.1.19.0 and verify if newer versions are available to ensure all known vulnerabilities in the middleware stack are resolved. In addition to patching, network-level controls such as Web Application Firewalls (WAF) can be configured to detect and block suspicious HTTP requests that exhibit patterns consistent with exploitation attempts against this vulnerability. It is also critical to review access control lists and firewall rules to ensure that Oracle Reports Developer interfaces are not exposed directly to untrusted networks like the public internet, but rather restricted to internal corporate networks or secured via VPN tunnels where possible. Regular security audits and penetration testing should be conducted to identify similar misconfigurations in other middleware components before they can be exploited by adversaries seeking lateral movement within the enterprise environment.
