AnalysisAIv1 – Sep 15, 2026

Unauthenticated information disclosure in Oracle iStore (Shopping Cart component) within Oracle E-Business Suite 12.2.3 through 12.2.15 lets a remote attacker with plain HTTP access read critical data exposed through the storefront, up to and including all data reachable by the iStore application. The flaw carries a CVSS 3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N, confidentiality-only impact) and is trivially automatable given the network vector and lack of credentials or user interaction. No CISA KEV entry, EPSS score, or public proof-of-concept was present in the supplied intelligence, so exploitation is assessed as possible but not confirmed in the wild at time of analysis.
