CVE-2026-47000 Overview
CVE-2026-47000 affects the Security Framework component of Oracle Enterprise Manager Base Platform version 24.1. The vulnerability is classified under [CWE-352] Cross-Site Request Forgery (CSRF). An authenticated attacker with low privileges can exploit this flaw over HTTPS when a targeted user interacts with attacker-supplied content. Successful exploitation allows unauthorized update, insert, or delete operations against a subset of Oracle Enterprise Manager Base Platform data. Confidentiality and availability are not impacted, and the scope remains unchanged.
Critical Impact
Successful exploitation permits unauthorized modification of Oracle Enterprise Manager data via forged HTTPS requests requiring victim interaction.
Affected Products
- Oracle Enterprise Manager Base Platform 24.1
- Oracle Enterprise Manager (Security Framework component)
- Deployments exposing the Enterprise Manager console over HTTPS

Technical Details for CVE-2026-47000
Vulnerability Analysis
The flaw is a Cross-Site Request Forgery (CSRF) weakness in the Security Framework of Oracle Enterprise Manager Base Platform 24.1. The application accepts state-changing HTTPS requests without adequately verifying that the request originated from a legitimate user action within the trusted session. When an authenticated administrator or operator visits an attacker-controlled resource, the browser automatically attaches session credentials to forged requests targeting Enterprise Manager endpoints.
The vulnerability requires the attacker to already hold a low-privileged account on the platform and to convince a second user to interact with malicious content. Impact is limited to integrity, allowing attackers to perform unauthorized update, insert, or delete actions on data reachable through the victim's session. Confidentiality and availability of managed systems remain unaffected.
Root Cause
The root cause is missing or insufficient anti-CSRF protection on state-changing endpoints within the Security Framework. Requests are processed based on session cookies without validating a per-request synchronizer token, origin header, or equivalent request provenance signal. This omission maps directly to [CWE-352].
Attack Vector
Exploitation follows the standard CSRF pattern. The attacker authenticates with a low-privileged account and stages a crafted HTML page, email, or link. When a higher-context Enterprise Manager user opens the attacker's content in a browser session that already holds valid Enterprise Manager cookies, the browser issues forged HTTPS POST or PUT requests. Enterprise Manager processes those requests as if the victim initiated them, modifying accessible data. The exploit requires network access, low privileges, and user interaction, but no elevated preconditions.
No public proof-of-concept or exploit code has been observed. Technical details are referenced in the Oracle Security Alert July 2026.
Detection Methods for CVE-2026-47000
Indicators of Compromise
- Enterprise Manager audit records showing configuration or data changes originating from unexpected Referer or Origin headers.
- HTTPS POST, PUT, or DELETE requests to Enterprise Manager endpoints lacking a valid anti-CSRF token parameter.
- Modification events on managed targets that do not correlate with a preceding console navigation flow for the same user.
Detection Strategies
- Inspect Enterprise Manager access logs for state-changing requests whose Referer header points to hosts outside the administrative domain.
- Correlate authenticated user sessions with browser activity to identify requests issued while the user was viewing external content.
- Alert on bursts of update, insert, or delete operations performed by accounts that historically only read data.
Monitoring Recommendations
- Enable and forward Oracle Enterprise Manager audit logs to a centralized SIEM for retention and correlation.
- Baseline normal administrative workflows so anomalous state-changing requests can be flagged in near real time.
- Monitor egress web proxy logs for administrator browser traffic to untrusted destinations during active EM sessions.
How to Mitigate CVE-2026-47000
Immediate Actions Required
- Apply the fixes distributed in the Oracle Critical Patch Update - July 2026 to Enterprise Manager Base Platform 24.1.
- Restrict Enterprise Manager console access to trusted management networks and jump hosts.
- Require administrators to use dedicated browser profiles or workstations that do not browse untrusted content while authenticated.
Patch Information
Oracle addressed CVE-2026-47000 in the July 2026 Critical Patch Update. Administrators should review the Oracle advisory to identify the specific patch bundle applicable to Oracle Enterprise Manager Base Platform 24.1 and apply it following Oracle's documented upgrade procedure. Verify patch application by confirming the reported component version after installation.
Workarounds
- Enforce short session timeouts and require re-authentication for sensitive administrative actions.
- Configure the Enterprise Manager reverse proxy or web tier to reject state-changing requests missing a valid Origin or Referer header matching the console hostname.
- Apply SameSite=Strict cookie attributes on session cookies where supported to limit cross-site cookie transmission.
- Educate administrators to log out of Enterprise Manager before browsing untrusted sites or opening unsolicited links.
