CVE-2026-62636 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 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via SOAP to compromise Oracle Reports Developer. 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 and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Reports Developer. CVSS 3.1 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L).

The identified vulnerability resides within the Oracle Reports Developer component of Oracle Fusion Middleware version 14.1.2.0.0, specifically affecting its Security and Authentication mechanisms. This flaw represents a critical failure in access control logic that permits unauthenticated actors to bypass intended security restrictions. The attack vector is network-based via SOAP, indicating that the vulnerability can be exploited remotely over standard web protocols without requiring user interaction or prior authentication credentials. Such an architecture exposes the application layer to direct exploitation by any entity capable of reaching the server's network interface, significantly expanding the potential threat surface beyond internal trusted networks to include public internet-facing deployments if not properly segmented.
From a technical perspective, the core issue is classified as CWE-287, Improper Authentication, which allows an attacker with no prior identity verification to execute actions reserved for authorized users. The exploitation of this flaw leads to severe consequences across multiple security dimensions. First, it results in high confidentiality impact, enabling unauthorized access to critical data stored or processed by the Oracle Reports Developer system. This means sensitive business intelligence, financial records, or proprietary reports could be exfiltrated without detection. Second, there is a low integrity impact, allowing attackers to perform unauthorized updates, inserts, or deletes on accessible data. This capability threatens the accuracy and reliability of reporting outputs, potentially leading to corrupted analytics or malicious manipulation of historical records. Third, availability is compromised through partial denial of service conditions, where successful exploitation can degrade system performance or render specific services unavailable to legitimate users.
The operational impact of this vulnerability aligns with MITRE ATT&CK techniques related to Initial Access and Credential Access. An attacker could leverage this flaw for unauthorized data access (T1078) or potentially use the ability to modify data as a precursor to persistence mechanisms if write permissions are sufficiently broad. The CVSS 3.1 base score of 8.6 reflects the high severity due to the combination of network accessibility, lack of required privileges, and significant impact on confidentiality alongside moderate impacts on integrity and availability. This scoring underscores the urgency for remediation as automated scanning tools can easily detect and exploit such misconfigurations or code flaws in real-time attacks.
Mitigation strategies must prioritize immediate patching by Oracle to apply the latest security updates that address this authentication bypass flaw. In environments where patching is not immediately feasible, network-level controls should be implemented to restrict SOAP endpoint access exclusively to trusted IP addresses using firewalls or web application firewalls. Additionally, implementing strict input validation and enforcing robust session management policies can help mitigate some aspects of the risk. Organizations must also conduct a thorough audit of their Oracle Reports Developer deployments to ensure no other instances are running on vulnerable versions and verify that default configurations have been hardened according to industry best practices for middleware security.
