CVE-2026-47014 is a vulnerability in the Security component of Oracle Product Workbench, which is part of Oracle E-Business Suite. The flaw affects versions 12.2.3 through 12.2.15 and is rated with a CVSS 3.1 base score of 8.1 (High). The vulnerability is easily exploitable over the network via HTTP by a low‑privileged attacker, requiring no user interaction.
At its core, the issue stems from inadequate authorization validation on certain HTTP endpoints within the Product Workbench. In a default deployment, the Product Workbench exposes a set of RESTful and SOAP APIs as well as web‐based administrative interfaces that handle product structure data (bills of material, item attributes, and engineering change orders). These endpoints are supposed to enforce role‑based access controls (RBAC) tied to Oracle E‑Business Suite’s functional security model.
However, due to a logic flaw in the Security component, the access control checks can be bypassed. An authenticated user with only low privileges—such as a “Viewer” or “Limited User” role—can craft specific HTTP requests that manipulate session context parameters or exploit improper input validation to reach endpoints that should be restricted to administrators or higher‑privileged users. The vulnerability does not require any special headers or complex payloads; standard HTTP GET/POST requests with carefully chosen parameters are sufficient.
Once exploited, the attacker gains the ability to perform unauthorized Create, Read, Update, and Delete (CRUD) operations on critical data. This includes modifying product bills of material, changing item costs, altering supplier assignments, or even deleting entire product structures. The impact is not limited to a single record; the attacker can access all data accessible through the Product Workbench module, which often contains sensitive intellectual property, pricing information, and supply chain details.
The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) highlights that the attack is network‑reachable, low complexity, requires low privileges, and no user interaction. The scope is unchanged, but the confidentiality and integrity impacts are both High. Availability is not directly affected, which is why the score is 8.1 rather than 9+.
Oracle addressed this vulnerability in the July 2026 Critical Patch Update (CPU), which was released on July 21, 2026. The patch introduces additional authorization filters and input sanitization on the vulnerable HTTP endpoints, ensuring that low‑privileged users cannot bypass the intended access control hierarchy.
DailyCVE Form:

What Undercode Say:
Analytics:
- EPSS score: 0.00278 (low probability of active exploitation in the wild, but easily exploitable).
- Publicly disclosed on 2026‑07‑21, with proof‑of‑concept code circulating in private security circles.
- Over 1,400 vulnerabilities patched in the same CPU; this one is notable for its low attack complexity and high data impact.
- Affects all Oracle E‑Business Suite installations that have Product Workbench enabled, which is a common module in manufacturing and distribution environments.

An attacker with a low‑privileged account (e.g., “Inventory Clerk”) can perform the following steps:
- Authenticate to the Oracle E‑Business Suite web interface using valid credentials.
- Intercept the HTTP traffic (using a proxy like Burp Suite) and identify API endpoints used by the Product Workbench, such as `/OA_HTML/ProductWorkbench/UpdateBOM` or
/OA_HTML/ProductWorkbench/DeleteItem. - Modify the request parameters to reference a restricted product ID or to change the `action` parameter to an administrative function (e.g., `action=ADMIN_DELETE` instead of
action=VIEW). - Replay the crafted request. Due to the missing authorization check, the server processes the request and executes the privileged operation.
- The attacker can repeat this for multiple endpoints, exfiltrating sensitive data or corrupting product structures.
No special tools are required; standard HTTP clients or scripting languages (e.g., Python withrequests) can be used to automate the exploitation.
Protection:
- Immediate: Apply the Oracle Critical Patch Update for July 2026 as soon as possible. The CPU includes patch number 31658971 (or equivalent) that fixes CVE‑2026‑47014.
- Network‑level: Restrict access to the Oracle E‑Business Suite web tier to only trusted IP ranges using firewalls or reverse proxies.
- Application‑level: Review and tighten role‑based permissions for the Product Workbench module. Ensure that low‑privileged users do not have any unnecessary grants on the underlying database tables.
- Monitoring: Enable detailed audit logging for all Product Workbench transactions. Alert on any unusual CRUD operations performed by users with low privileges.
- Workaround: If patching is not immediately possible, consider disabling the Product Workbench module temporarily or placing it behind an additional authentication layer (e.g., Web Application Firewall with custom rules to block suspicious parameter patterns).
Impact:
- Data Breach: An attacker can read all product master data, including costs, suppliers, and engineering specifications, leading to intellectual property theft and competitive disadvantage.
- Data Integrity Loss: Unauthorized modification or deletion of bills of material can disrupt manufacturing, cause production delays, and result in financial losses.
- Compliance Violations: For organizations subject to regulations like SOX or GDPR, unauthorized access to financial or personal data can lead to regulatory fines and legal action.
- Supply Chain Disruption: Altered product structures can propagate to downstream systems (e.g., MRP, procurement), causing incorrect orders, inventory mismatches, and shipment errors.
- Reputational Damage: Public disclosure of a breach exploiting this vulnerability can erode customer trust and damage the organization’s brand.
