CVE-2026-70672 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. Difficult to exploit 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 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Security and Authentication component of Oracle Reports Developer, specifically affecting version 14.1.2.0.0 as part of the Oracle Fusion Middleware suite. This flaw represents a critical security deficiency that undermines the fundamental integrity of the application's access control mechanisms. The nature of this weakness allows an attacker to bypass authentication requirements entirely, granting them unauthenticated access to sensitive system functions and data stores. Such a scenario is particularly dangerous because it removes the primary barrier between external actors and internal enterprise resources, effectively turning the reporting infrastructure into an open gateway for malicious activity without requiring valid credentials or user interaction.
From a technical perspective, this vulnerability enables unauthorized creation, deletion, or modification of critical data accessible through Oracle Reports Developer. The impact extends beyond mere data alteration to include complete unauthorized access to all data that the application is configured to retrieve and display. This level of compromise suggests a failure in input validation or session management logic within the HTTP handling subsystem. An attacker leveraging this flaw can manipulate report definitions, alter underlying database queries executed by the reports engine, or exfiltrate sensitive information directly through the reporting interface. The absence of required authentication means that any entity with network connectivity to the service port hosting Oracle Reports Developer can attempt exploitation, significantly expanding the attack surface beyond trusted internal networks to potentially include internet-facing deployments if not properly segmented.
The operational impact of this vulnerability is severe, characterized by high confidentiality and integrity impacts as reflected in its CVSS 3.1 base score of 7.4. The specific vector indicates that while the attack complexity is rated as high due to difficult exploitation conditions, the availability requirement for success is low since no user interaction or privileges are needed prior to the attack. This combination means that once an attacker identifies a vulnerable instance and crafts the appropriate exploit payload, they can achieve significant damage with relative ease compared to vulnerabilities requiring complex social engineering or local access. The resulting data breach could lead to regulatory non-compliance, financial loss, reputational damage, and operational disruption depending on the sensitivity of the reports being accessed or modified.
In terms of industry standard classifications, this vulnerability aligns closely with CWE-287 Improper Authentication, where an actor is able to bypass authentication mechanisms to gain access to restricted resources. It also relates to CWE-601 URL Redirection to Untrusted Site in a Security Context if the exploitation involves redirecting users or data flows through malicious intermediaries, though the primary issue remains the lack of required credentials for sensitive operations. Furthermore, from an ATT&CK perspective, this flaw facilitates Initial Access via Exploitation of Remote Services and potentially Credential Access if session tokens are intercepted during the unauthenticated interaction phase. The ability to modify critical data also touches upon Persistence or Impact categories depending on whether the attacker leaves backdoors or destroys information integrity for malicious purposes.
Mitigation strategies must prioritize immediate remediation through vendor-provided patches, as Oracle has likely released updates addressing this specific authentication bypass in subsequent releases of Fusion Middleware 14c. Organizations should verify their current version and apply the latest security bundle patch immediately to close the gap. In environments where patching is not instantly feasible, network-level controls such as Web Application Firewalls can be configured to block requests that exhibit patterns associated with unauthenticated access attempts or known exploit signatures targeting this component. Additionally, restricting HTTP access to Oracle Reports Developer strictly to trusted internal IP ranges via firewall rules reduces the exposure surface significantly. Regular security audits and penetration testing focused on authentication flows are recommended to ensure no similar weaknesses exist in related modules of the middleware stack.
