AnalysisAIv1 – Sep 15, 2026

Oracle Bills of Material, a module within Oracle E-Business Suite 12.2.3 through 12.2.15, exposes an Internal Operations component that fails to properly restrict what a low-privileged authenticated user can do over HTTP. An attacker holding any valid low-privilege E-Business Suite account can send crafted HTTP requests that read all Bills of Material data and create, delete, or modify it, giving full confidentiality and integrity compromise of the module's records without any user interaction. At the time of analysis there is no CISA KEV listing, no public exploit code identified, and no EPSS score supplied, so the practical near-term risk is driven by whether the target EBS instance is internet-facing or reachable from a compromised low-privilege account.
