CVE-2026-70797 Overview
CVE-2026-70797 is a vulnerability in the Oracle Purchasing product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A high-privileged attacker with network access via HTTP can exploit this vulnerability with low attack complexity. Successful exploitation results in full takeover of Oracle Purchasing, compromising confidentiality, integrity, and availability of the application.
Critical Impact
Successful exploitation allows a high-privileged authenticated attacker to take over the Oracle Purchasing application, gaining full control over sensitive procurement data and internal operations.

Technical Details for CVE-2026-70797
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle Purchasing, part of Oracle E-Business Suite. Oracle describes the flaw as easily exploitable over HTTP by an attacker holding high privileges within the application. Once exploited, the attacker achieves complete takeover of Oracle Purchasing. This means the adversary can read, modify, and disrupt procurement records, purchase orders, supplier data, and related internal operations. Because Oracle Purchasing typically integrates with financial and supply-chain modules, the compromise can extend the impact across downstream business processes.
Root Cause
Oracle has not publicly disclosed the underlying technical defect for CVE-2026-70797. No Common Weakness Enumeration (CWE) classification has been assigned in the NVD entry. Refer to the Oracle Security Alert for vendor-provided details.
Attack Vector
The attack is delivered over the network using HTTP against the affected Oracle Purchasing instance. The attacker must already hold high privileges in the application before exploitation. No user interaction is required, and the scope remains unchanged. The vulnerability does not require authentication bypass; instead, it enables an authorized user with elevated access to escalate to complete application takeover.
No verified public proof-of-concept exploit code is available for CVE-2026-70797. See the Oracle Security Alert for authoritative details.
Detection Methods for CVE-2026-70797
Indicators of Compromise
- Unexpected creation or modification of purchase orders, requisitions, or supplier records by privileged accounts outside normal business hours.
- Anomalous HTTP requests to Oracle Purchasing Internal Operations endpoints originating from unusual client IPs or user agents.
- Application audit-log entries showing privileged user actions inconsistent with historical baseline activity.
Detection Strategies
- Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to identify abuse of high-privileged accounts.
- Correlate application-tier HTTP access logs with database-tier audit records to identify privileged operations executed through unexpected sessions.
- Alert on privilege changes, new responsibilities being assigned, or unusual concurrent-program submissions within the Purchasing module.
Monitoring Recommendations
- Forward Oracle E-Business Suite application, middle-tier, and database logs to a centralized SIEM for continuous analysis.
- Baseline normal behavior for privileged Purchasing users and generate alerts on statistical deviations.
- Monitor outbound network traffic from the Oracle E-Business Suite application tier for unexpected connections that may indicate post-exploitation activity.
How to Mitigate CVE-2026-70797
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert to all affected Oracle E-Business Suite 12.2.3 through 12.2.15 environments.
- Audit and reduce the number of accounts holding high privileges within Oracle Purchasing to enforce least privilege.
- Rotate credentials for all privileged Purchasing users and enforce strong authentication controls.
Patch Information
Oracle has published remediation guidance in the August 2026 Oracle Security Alert. Administrators should consult the Oracle Security Alert advisory for the specific patch bundles applicable to their Oracle E-Business Suite deployment and apply them following Oracle's standard patching methodology.
Workarounds
- Restrict network access to Oracle E-Business Suite HTTP endpoints using firewall rules, allowing only trusted internal networks and VPN clients.
- Place the Oracle Purchasing application behind a Web Application Firewall (WAF) that inspects HTTP traffic to the Internal Operations component.
- Temporarily suspend or restrict responsibilities that grant high privileges within Oracle Purchasing until patches are applied.
# Example: restrict HTTP access to the Oracle E-Business Suite application tier
# Replace the source range with the trusted administrative network
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
