AnalysisAIv1 – Sep 15, 2026

Oracle E-Business Suite 12.2.11 through 12.2.15 ships a flaw in the G-Invoicing component of Oracle Purchasing that lets an authenticated, low-privileged user reach data and functions they should not control over plain HTTP. Successful exploitation gives full read and write reach into Purchasing data — creation, modification, and deletion of critical records plus complete disclosure of everything the module can access — with no user interaction required. Oracle rates it CVSS 8.1 (C:H/I:H/A:N, PR:L), but no EPSS score, CISA KEV entry, or public exploit code was present in the supplied intelligence, so active exploitation is unconfirmed and the practical risk is best judged against the wide enterprise footprint of EBS Purchasing.
