Summary
CVE-2026-62636 is a vulnerability in the authentication mechanism of Oracle Reports Developer that can be exploited over the network via the SOAP protocol without requiring any credentials or user interaction. Successful exploitation gives an attacker unauthorized access to data handled by Oracle Reports Developer, the ability to make unauthorized modifications, and the ability to cause partial denial of service. The flaw carries a CVSS v3.1 base score of 8.6 (High).
Technical details
- Root cause: A weakness in Oracle Reports Developer’s authentication handling that can be bypassed when the SOAP interface is reached.
- Trigger conditions: No authentication and no user interaction are required to exploit the flaw.
- Attack vector: Network-based; the attacker sends requests to the exposed SOAP interface of Oracle Reports Developer.
- Impact: High confidentiality impact (unauthorized access to, or complete access to, all data accessible to Oracle Reports Developer), low integrity impact (unauthorized data modification), and low availability impact (partial denial of service).
Affected software
- Oracle Reports Developer version 14.1.2.0.0
Severity
- CVSS v3.1 Base Score: 8.6 (High)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L
Mitigation and recommended actions
- Immediate: Apply the fix provided in Oracle’s Critical Security Patch Update advisory for August 2026, which addresses CVE-2026-62636 for Oracle Reports Developer 14.1.2.0.0.
- If patching cannot be performed immediately: Restrict or disable network access to the Oracle Reports Developer SOAP interface from untrusted networks (e.g., via firewall rules or reverse proxy access controls) until the patch is applied, and monitor for unexpected SOAP requests to internet-facing Reports Developer endpoints.
