CVE-2026-83122

CVE-2026-83122 is a high-severity flaw in the Internal Operations component of Oracle Report Manager, part of Oracle E-Business Suite, affecting releases 12.2.3 through 12.2.15. It is easily exploitable over the network via HTTPS by an attacker holding only a low-privileged (authenticated) account, requiring no user interaction. A successful attack lets the attacker fully compromise Oracle Report Manager, with high impact on the confidentiality, integrity, and availability of the component. Because EBS is widely deployed at large enterprises and often internet-facing for partner/self-service access, any 12.2.x environment exposing Report Manager to users beyond trusted internal staff is at risk. No public proof-of-concept exists, the issue is not on CISA's KEV list, and no exploitation in the wild is currently known.

What to do: Apply the Oracle Critical Patch Update that remediates CVE-2026-83122 to every E-Business Suite environment running 12.2.3-12.2.15. Until patched, restrict HTTPS access to the Report Manager / Internal Operations endpoints to trusted networks (VPN or IP allowlisting) and enforce least-privilege account provisioning. Review logs for anomalous activity by low-privileged accounts against Report Manager to rule out prior exploitation.
