CVE-2026-46853Network attack vector

Unauthenticated takeover via Metadata Plugin XSS

Published Jun 16, 2026 · Updated Jun 16, 2026

Cross-site scripting in Oracle Enterprise Manager Base Platform 13.5 and 24.1 allows remote attackers to take over the platform via HTTP. Oracle identifies the Metadata Plugin and maps the issue to CWE-79 but does not disclose the affected handler, input, or output-encoding failure. Exploitation requires a separate user to interact with content controlled by remote attackers, after which the platform and connected products can be affected.
