CVE-2026-62620 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. 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).

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 versions depending on configuration. This security flaw is categorized under Security and Authentication mechanisms, indicating a failure in the system's ability to properly verify user identity or enforce access controls before granting entry to sensitive resources. The nature of this vulnerability allows for exploitation by an unauthenticated attacker who possesses network access via HTTP, meaning no prior credentials are required to initiate an attack vector against the affected service. This characteristic significantly lowers the barrier to entry for malicious actors, as it eliminates the need for social engineering or credential theft phases typically associated with more complex authentication bypasses.
From a technical perspective, this flaw represents a critical breakdown in access control logic within the web-based interface of Oracle Reports Developer. The vulnerability likely stems from improper validation of incoming HTTP requests, allowing an attacker to manipulate parameters or headers to trigger unauthorized operations or retrieve restricted data without passing through standard authentication gates. This type of defect is commonly associated with CWE-287, which describes Improper Authentication, and often overlaps with CWE-306, Missing Authentication for Critical Function, where the system fails to require authentication for a function that has implications beyond the user's immediate scope. The presence of such a flaw suggests that internal API endpoints or administrative interfaces may be exposed without adequate protective measures, creating a direct pathway into the core functionality of the reporting engine.
The operational impact of this vulnerability is severe due to its high confidentiality impact score and potential for scope change. While the technical root cause lies within Oracle Reports Developer, successful exploitation can lead to significant lateral movement or data exfiltration from additional products that share underlying infrastructure or database connections with the middleware suite. An attacker gaining unauthorized access could retrieve critical business intelligence reports, customer databases, financial records, or proprietary algorithms stored within the reporting repository. The CVSS 3.1 base score of 8.6 reflects this high severity, driven primarily by the complete loss of confidentiality for accessible data. Although integrity and availability impacts are currently assessed as negligible in the standard vector, the unauthorized access itself constitutes a major breach of security posture, potentially violating regulatory compliance standards such as GDPR, HIPAA, or PCI-DSS depending on the nature of the exposed data.
In terms of threat modeling, this vulnerability aligns with MITRE ATT&CK techniques related to Initial Access and Discovery. Specifically, it resembles T1078 Valid Accounts if credentials were involved, but since it is unauthenticated, it falls closer to T1190 Exploit Public-Facing Application or potentially T1506 Post-Compromise Discovery if the attacker uses the initial access to map out further targets within the environment. The ability of attacks to significantly impact additional products highlights a risk in architectural design where shared components create single points of failure that can cascade across multiple services, amplifying the blast radius beyond the initially targeted application.
To mitigate this vulnerability, organizations must immediately apply the latest security patches provided by Oracle for Oracle Fusion Middleware version 12.2.1.19.0 and subsequent updates. It is critical to verify that all instances of Oracle Reports Developer are updated to a patched release where the authentication logic has been hardened. In addition to patching, network-level controls should be implemented to restrict access to these services exclusively from trusted IP addresses or internal networks using firewalls or reverse proxies with strict ACLs. Enabling HTTPS and disabling HTTP-only access can also reduce exposure if the vulnerability is tied specifically to unencrypted channels, although authentication fixes are paramount. Regular security audits and penetration testing focused on web application vulnerabilities should be conducted to identify similar misconfigurations in other middleware components before they can be exploited by adversaries seeking initial footholds within the enterprise network.
