CVE-2026-62616 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 SMTP 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 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 7.2 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L).

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 but manifests through an interface that accepts Simple Mail Transfer Protocol traffic. The core technical issue involves a failure in input validation or state management within the SMTP handling subsystem, which allows unauthenticated actors to interact with internal application logic without prior credential verification. Because Oracle Fusion Middleware products are often deployed as part of larger enterprise ecosystems where components share underlying infrastructure and data stores, an exploit targeting this specific component can lead to scope changes. This means that while the direct vulnerability is in Reports Developer, the resulting compromise may cascade into adjacent services or databases integrated with the middleware environment, thereby expanding the blast radius beyond the immediate application boundary.
From a technical perspective, the exploitation vector relies on network accessibility via SMTP, which typically operates over port 25 or its secure variants. The attacker does not require user interaction or complex preconditions to initiate an attack, as indicated by the low complexity and absence of required user interface elements in the CVSS scoring model. Once triggered, the vulnerability enables unauthorized modifications to accessible data within Oracle Reports Developer. This includes the ability to perform insertions, updates, or deletions against database records that are exposed through the reporting engine. Such actions directly compromise the integrity of business-critical reports and underlying datasets. Furthermore, the flaw allows for partial denial of service conditions, likely by exhausting system resources such as memory or connection pools through malformed SMTP requests, thereby disrupting availability for legitimate users attempting to access report generation services.
The operational impact is significant due to the high base score of 7.2 on the CVSS v3.1 scale, reflecting substantial risks to both integrity and availability while leaving confidentiality largely unaffected in this specific vector. The unauthorized data manipulation poses severe business continuity and compliance risks, particularly for organizations relying on Oracle Reports for regulatory reporting or financial analysis where data accuracy is paramount. A partial denial of service further degrades operational efficiency by rendering the reporting infrastructure intermittently unavailable during attack periods. This aligns with Common Weakness Enumeration categories such as CWE-20 Improper Input Validation and CWE-436 Interpretation Conflict, suggesting that the application fails to correctly sanitize or interpret incoming SMTP data structures. In terms of offensive security frameworks like MITRE ATT&CK, this vulnerability facilitates techniques related to Initial Access via email-based vectors if misconfigured, but more critically enables Lateral Movement through shared infrastructure compromise and Impact activities including Data Manipulation and Service Stoppage.
Mitigation strategies must prioritize immediate patching to the latest available version of Oracle Fusion Middleware that addresses this specific flaw in the Reports Developer SMTP handler. Organizations should also implement network-level controls such as firewall rules or access control lists to restrict inbound SMTP traffic to trusted internal subnets only, preventing direct exposure to unauthenticated external attackers if possible. Additionally, deploying intrusion detection systems configured with signatures for known exploitation patterns of Oracle middleware vulnerabilities can provide an additional layer of defense in depth. Regular auditing of authentication logs and monitoring for anomalous spikes in SMTP transaction volumes or unusual database write operations from the Reports Developer service account are recommended operational security practices to detect potential exploitation attempts early.
