CVE-2026-61306Network attack vector

Unauthorized data access and partial service interrupt

Published Aug 18, 2026 · Updated Aug 19, 2026

Access control vulnerability in Oracle Complex Maintenance, Repair and Overhaul 12.2.3-12.2.15 allows remote authenticated users to read data. Oracle lists the affected Production component and CWE-284, but neither the Oracle advisory nor the published CVE record identifies the code path or the specific authorization check that mishandles attacker-supplied requests. Exploitation requires low-privileged network access over HTTP and is described as high-complexity; successful attacks expose critical or all accessible data and can also cause a partial service interrupt, with stated scope change into additional products.
