CVE-2026-87126 in Report Manager
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Report Manager product of Oracle E-Business Suite (component: Reports Security). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Report Manager. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Report Manager accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Report Manager. CVSS 3.1 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).

The identified vulnerability resides within the Reports Security component of Oracle Report Manager, a critical module in the Oracle E-Business Suite ecosystem. This security flaw affects multiple supported versions ranging from 12.2.3 through 12.2.15, indicating a systemic issue rather than an isolated incident in specific releases. The nature of this vulnerability is particularly concerning because it allows for exploitation by attackers with low privileges who possess network access via the HTTP protocol. This means that authentication bypass or privilege escalation mechanisms are insufficient to prevent unauthorized actors from interacting with the vulnerable components over standard web ports, significantly expanding the attack surface beyond internal networks to potentially any internet-facing deployment where Oracle Report Manager is accessible.
From a technical perspective, the flaw enables an attacker to compromise the integrity and confidentiality of the data managed by Oracle Report Manager without requiring high-level administrative credentials or complex user interaction. The absence of required user interface interactions simplifies automated exploitation techniques, allowing for rapid scanning and attack campaigns across vulnerable environments. The vulnerability primarily impacts two core security principles: confidentiality and availability. In terms of confidentiality, successful exploitation grants unauthorized access to critical data stored within the reporting infrastructure. This can include sensitive financial records, customer information, or proprietary business intelligence reports that are generated and stored by the system. For organizations relying on Oracle E-Business Suite for mission-critical operations, such a breach represents a significant risk to regulatory compliance and corporate reputation.
The availability impact of this vulnerability is equally severe, as it allows an attacker to cause a partial denial of service against Oracle Report Manager. While not necessarily causing a complete system crash, the ability to disrupt services can lead to operational downtime, preventing authorized users from generating necessary reports or accessing historical data. This disruption can halt business processes that depend on timely reporting and analytics. The combination of unauthorized data access and service degradation creates a multifaceted threat landscape where attackers can exfiltrate sensitive information while simultaneously degrading the utility of the system for legitimate users, thereby maximizing the impact of their intrusion.
In terms of industry-standard classification frameworks, this vulnerability aligns with CWE-284 Improper Access Control or potentially CWE-798 if it involves hardcoded credentials or excessive privileges in configuration files that are exposed via HTTP. The attack vector corresponds to MITRE ATT&CK techniques related to Initial Access through web applications and potentially Persistence or Privilege Escalation depending on the specific exploitation path used by attackers. Security professionals should treat this as a high-priority issue due to its network accessibility, low complexity of exploitation, and significant impact on both data confidentiality and system availability.
Mitigation strategies must focus on immediate patching and access control hardening. Organizations running affected versions of Oracle E-Business Suite should apply the latest security patches provided by Oracle for their specific version range from 12.2.3 to 12.2.15. Until patches are applied, it is advisable to restrict network access to Oracle Report Manager components using firewalls or web application firewalls that can filter malicious HTTP requests associated with this vulnerability. Additionally, implementing strict authentication policies and monitoring for unusual activity patterns in the reports module can help detect attempted exploitation early. Regular audits of user privileges ensure that only necessary accounts have access to sensitive reporting functions, reducing the potential impact if a low-privileged account is compromised.
