AnalysisAIv1 – Sep 15, 2026

A low-privileged authenticated attacker with HTTP access to the Oracle Bills of Material module in Oracle E-Business Suite 12.2.3 through 12.2.15 can read critical Bills of Material data beyond their authorization and partially degrade availability of the module, with the impact extending into other, additional Oracle products (scope change). Oracle rates this 8.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L) in its 2026 Critical Security Patch Update advisory, and the flaw is considered easily exploitable because it needs no user interaction or complex timing. No public exploit code has been identified and the vulnerability is not listed in CISA KEV; no EPSS score or POC reference was supplied with the intelligence for this analysis.
