CVE-2026-62610 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. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Reports Developer accessible data as well as unauthorized access to critical data or complete access to all Oracle Reports Developer accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/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 in that lineage. This security flaw is categorized under Security and Authentication mechanisms, indicating a fundamental failure in how the application verifies user identity or manages session states before granting access to sensitive resources. The nature of this vulnerability allows for exploitation by an unauthenticated attacker who possesses network connectivity via HTTP. This implies that no prior login credentials are required to initiate an attack vector against the service, significantly lowering the barrier to entry for malicious actors and increasing the likelihood of widespread compromise in environments where the application is exposed to internal or external networks without sufficient perimeter controls.
From a technical perspective, the vulnerability likely stems from insufficient validation of input parameters or improper enforcement of access control policies within the HTTP request handling logic. An attacker can craft specific network requests that bypass authentication checks, effectively tricking the server into executing privileged operations as if they were performed by an authorized administrator or user. This type of flaw is commonly associated with broken object level authorization or insecure direct object references where the system fails to verify that the requesting entity has permission to access the targeted data objects. The ease of exploitation suggests a lack of complex prerequisites, meaning automated scanning tools and script kiddies can leverage this weakness without needing specialized knowledge beyond standard web interaction protocols.
The operational impact of successfully exploiting this vulnerability is severe, as indicated by the high CVSS 3.1 Base Score of 9.1. The primary consequences involve unauthorized creation, deletion, or modification of critical data stored within Oracle Reports Developer and all accessible datasets associated with it. This represents a catastrophic breach of both confidentiality and integrity principles in information security. Attackers can exfiltrate sensitive business intelligence reports, customer records, financial data, or proprietary algorithms contained within the reporting database. Furthermore, they may alter existing reports to mislead decision-makers or delete critical historical data, causing operational disruption and potential regulatory non-compliance depending on the industry sector involved. The absence of an availability impact in the CVSS vector suggests that while data integrity is compromised, the service itself might remain technically accessible, though its trustworthiness would be entirely nullified.
In terms of classification standards, this vulnerability aligns with CWE-287 Improper Authentication and CWE-918 Server-Side Request Forgery if the exploitation involves leveraging server-side processing to access internal resources. It also maps closely to MITRE ATT&CK techniques such as T1078 Valid Accounts or T1530 Data from Cloud Storage, depending on whether the attacker uses stolen credentials via this flaw or directly accesses cloud-backed data stores through the compromised application interface. The attack pattern typically falls under initial access vectors where adversaries gain a foothold in an organization's network by exploiting publicly accessible applications with known vulnerabilities.
Mitigation strategies must be implemented immediately to reduce the risk surface. Oracle should apply the latest security patches and updates provided for Fusion Middleware version 12.2.1.x, which address these authentication bypass flaws. In the interim, organizations running this software should restrict HTTP access to the Reports Developer service using network segmentation or firewall rules that limit connectivity to trusted IP addresses only. Implementing a Web Application Firewall can also help by inspecting incoming traffic for patterns indicative of exploitation attempts related to parameter manipulation and unauthorized API calls. Additionally, enabling comprehensive logging and monitoring on the middleware servers is crucial for detecting anomalous access patterns that may indicate an ongoing attack. Regular audits of user permissions and adherence to the principle of least privilege will further harden the environment against such unauthenticated intrusion attempts.
