CVE-2026-62628 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 TCP 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 connectivity via TCP protocols. This means that no prior authentication credentials are required to initiate an attack vector against the affected service, significantly lowering the barrier to entry for malicious actors and increasing the likelihood of successful compromise in environments where such services are exposed to internal or external networks without adequate perimeter defenses.
The technical flaw enables unauthorized access to critical data stored within the Oracle Reports Developer environment. Upon successful exploitation, an attacker can bypass authentication checks to retrieve sensitive information that should be restricted to authorized users only. The impact is primarily focused on confidentiality, as indicated by a CVSS 3.1 Base Score of 8.6 with high impacts on confidentiality but no direct impact on integrity or availability in the base score calculation. However, it is crucial to note that while the vulnerability is technically located within Oracle Reports Developer, the scope change warning indicates that attacks may significantly impact additional products. This suggests a potential chain reaction where compromising this component could lead to lateral movement or privilege escalation into other integrated systems within the Fusion Middleware ecosystem, thereby expanding the blast radius of the initial breach beyond the immediate application layer.
From an industry standard perspective, this vulnerability aligns with CWE-287 Improper Authentication and potentially CWE-306 Missing Authentication for Critical Function if the specific mechanism involves a lack of required credentials for certain administrative or data retrieval functions. In terms of offensive security tactics, this scenario maps to MITRE ATT&CK technique T1078 Valid Accounts if the attacker leverages stolen credentials obtained through other means, but more accurately reflects T1190 Exploit Public-Facing Application given the network-accessible nature and unauthenticated exploitability. The high confidentiality impact underscores the risk of data exfiltration, which could lead to regulatory violations under frameworks such as GDPR or HIPAA if personal health information or personally identifiable information is exposed through this vector.
Mitigation strategies must prioritize immediate isolation and patching. Organizations running Oracle Fusion Middleware version 12.2.1.19.0 should apply the latest security patches provided by Oracle immediately to address the authentication bypass flaw. In addition to applying vendor-supplied updates, it is imperative to review network architecture to ensure that Oracle Reports Developer services are not directly exposed to untrusted networks via TCP without robust intermediary controls such as Web Application Firewalls or reverse proxies with strict access control lists. Implementing zero-trust principles where every request is authenticated and authorized regardless of origin can further mitigate the risk posed by this vulnerability. Regular security assessments and penetration testing should be conducted to identify similar misconfigurations in authentication mechanisms across the middleware stack, ensuring that no other components suffer from comparable weaknesses that could facilitate unauthorized data access or broader system compromise.
