## Technical details

This vulnerability affects the Internal Operations component of Oracle iSupport within Oracle E-Business Suite versions 12.2.3 through 12.2.15. It is classified as an easily exploitable flaw that requires high administrative privileges (PR:H) but no user interaction. The attack vector is network-based via HTTP. A successful exploit results in a 'scope change' (S:C), meaning the attacker can move beyond the iSupport component to impact other parts of the E-Business Suite environment, leading to a total loss of confidentiality, integrity, and availability. Oracle has addressed this in their June 2026 security update.
