## Technical details

A vulnerability classified as Cross-Site Scripting (XSS) exists in the Metadata Plugin component of Oracle Enterprise Manager Base Platform (versions 13.5 and 24.1). The flaw (CWE-79) allows an unauthenticated remote attacker to send a malicious HTTP request that, when processed by a victim's browser, can lead to a full compromise of the platform. Although the attack vector is network-based and requires no privileges, it does require human interaction (UI:R) from a user other than the attacker. The vulnerability includes a scope change (S:C), meaning a successful exploit can impact security components beyond the immediate Oracle Enterprise Manager environment. Oracle has addressed this in the June 2026 security alerts.
