CVE-2026-62621: Vulnerability in the Oracle Reports Developer product of Oracle Fusion Middleware (component: Security and...
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. Successful attacks of this vulnerability can result in takeover of Oracle Reports Developer. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Security readout for executives and security teams
Plain-English summary
A network-accessible attacker can compromise Oracle Reports Developer without credentials or user interaction. Successful exploitation could give the attacker complete control, threatening sensitive reports, data integrity, and service availability. The supplied evidence limits affected systems to version 12.2.1.19.0.
Executive priority
Treat this as an immediate remediation priority for reachable version 12.2.1.19.0 systems. The combination of unauthenticated network access and potential complete takeover creates material operational and data risk. Prioritize internet-facing deployments, restrict access promptly, and require confirmation that Oracle guidance has been applied.
Technical view
CVE-2026-62621 is a CWE-284 access-control vulnerability in Oracle Reports Developer’s Security and Authentication component. It is remotely reachable over TCP, requires low attack complexity, no privileges, and no user interaction. Oracle assigns CVSS 3.1 score 9.8, with high confidentiality, integrity, and availability impacts.
Likely exposure
Exposure exists where Oracle Reports Developer 12.2.1.19.0 is installed and reachable by an attacker over TCP. Internet-facing or broadly accessible deployments warrant the fastest review. The supplied sources do not identify other affected versions, ports, configurations, or prerequisites.
Exploitation context
The vulnerability is described as easily exploitable and capable of product takeover. However, it is not listed as KEV in the supplied bundle, and no cited source provides evidence of active exploitation or public exploit availability. Absence from KEV does not establish that exploitation has not occurred.
Researcher notes
The supplied record identifies the vulnerable component and impact but does not provide the vulnerable function, protocol details beyond TCP, indicators of compromise, exploit mechanics, or a named patch. Validation should remain version- and exposure-focused while Oracle’s advisory is checked for authoritative remediation details.
Mitigation direction
Inventory Oracle Reports Developer installations and identify version 12.2.1.19.0.
Review Oracle’s advisory for prescribed updates or mitigations; test and deploy applicable vendor guidance.
Restrict TCP access to trusted systems and administrators until vendor remediation is confirmed.
Isolate externally reachable instances and apply least-privilege network controls.
Increase monitoring for unexpected access or administrative activity involving affected systems.
Validation and detection
Confirm installed Oracle Reports Developer versions using approved asset and configuration records.
Map TCP reachability from internet-facing, partner, user, and management network segments.
Verify vendor-prescribed remediation is installed and recorded on every affected instance.
Review authentication, network, and administrative logs for unexplained access or configuration changes.
Reassess network exposure after remediation and confirm unnecessary access paths are blocked.
