AnalysisAIv1 – Sep 15, 2026

Authenticated attackers holding only low-privileged credentials in Oracle E-Business Suite can exploit a WebUI flaw in Oracle Product Workbench 12.2.3 through 12.2.15 to read and tamper with application data, provided they can convince another user to interact with a crafted request. The CVSS 3.1 base score is 5.4 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N), with a scope change meaning downstream components of the E-Business Suite may also be affected. No public exploit code or active exploitation has been identified in the supplied intelligence, and no EPSS score was provided.
