CVE-2026-70809 Overview
CVE-2026-70809 is a broken access control vulnerability [CWE-284] in the Oracle Scripting 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 low-privileged attacker with network access via HTTP can exploit the vulnerability to compromise Oracle Scripting, though exploitation is rated difficult by the vendor. Successful exploitation enables unauthorized read, creation, modification, or deletion of Oracle Scripting data and can cause a partial denial of service. Oracle addressed the issue in the Oracle Security Alert - August 2026.
Critical Impact
Authenticated network attackers can gain full read and write access to Oracle Scripting data and degrade service availability across affected Oracle E-Business Suite deployments.
Affected Products
- Oracle E-Business Suite - Oracle Scripting version 12.2.3
- Oracle E-Business Suite - Oracle Scripting versions 12.2.4 through 12.2.14
- Oracle E-Business Suite - Oracle Scripting version 12.2.15

Technical Details for CVE-2026-70809
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle Scripting, part of the broader Oracle E-Business Suite platform. An authenticated attacker with low privileges can send crafted HTTP requests that bypass intended access restrictions. Once the access control check is subverted, the attacker gains the ability to read, create, modify, or delete data across the Oracle Scripting module. The same request path also allows the attacker to disrupt scripting operations, producing a partial denial of service against the module.
Attack complexity is rated high, indicating the attacker must satisfy specific runtime conditions or authentication context before the request succeeds. However, the scope of accessible data once exploited covers all Oracle Scripting accessible records, making the confidentiality and integrity impact substantial for any organization using survey scripting, campaign scripting, or agent-facing scripts in E-Business Suite.
Root Cause
The issue maps to CWE-284 (Improper Access Control). The Internal Operations component does not enforce sufficient authorization checks on requests that reach privileged scripting operations. Low-privileged users receive functional access to actions that should be restricted to administrators or scoped by object ownership.
Attack Vector
Exploitation requires network reachability to the E-Business Suite HTTP tier and a valid low-privileged account. The attacker issues HTTP requests to Oracle Scripting endpoints exposed by the Internal Operations component. Because no user interaction is required and the flaw is exploitable over the network, any accessible E-Business Suite deployment with authenticated user access represents an exposure. Oracle has not published exploitation details, and no public proof-of-concept is currently listed. Refer to the Oracle Security Alert - August 2026 for vendor guidance.
Detection Methods for CVE-2026-70809
Indicators of Compromise
- Unexpected create, update, or delete operations against Oracle Scripting tables performed by low-privileged application users.
- HTTP requests to Oracle Scripting Internal Operations endpoints originating from user accounts that do not normally interact with those URIs.
- Partial service degradation or timeouts in Oracle Scripting workflows without corresponding infrastructure incidents.
Detection Strategies
- Enable Oracle E-Business Suite auditing on Scripting-related tables and review changes attributed to accounts without scripting administration roles.
- Correlate application-tier HTTP access logs with database change events to identify authorization bypass patterns.
- Baseline normal Oracle Scripting request rates per user and alert on statistical outliers.
Monitoring Recommendations
- Forward E-Business Suite middle-tier and database audit logs to a centralized SIEM for cross-source correlation.
- Monitor for anomalous session behavior from low-privileged EBS accounts, particularly HTTP POST activity to Scripting endpoints.
- Track error and exception rates in Oracle Scripting to detect partial denial-of-service conditions early.
How to Mitigate CVE-2026-70809
Immediate Actions Required
- Apply the security patches from the Oracle Security Alert - August 2026 to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
- Inventory user accounts with access to Oracle Scripting and remove privileges from accounts that do not require them.
- Restrict network access to the E-Business Suite HTTP tier so only trusted internal networks and VPN clients can reach it.
Patch Information
Oracle issued the fix as part of the August 2026 Critical Patch Update cycle. Administrators should review the Oracle Security Alert - August 2026 advisory, apply the referenced patch for Oracle Scripting in E-Business Suite 12.2, and validate the patch level in the environment after installation.
Workarounds
- If immediate patching is not feasible, restrict access to Oracle Scripting Internal Operations endpoints at the web application firewall or reverse proxy level.
- Enforce least-privilege role assignments for all Oracle Scripting users and remove standing access from shared or service accounts.
- Increase audit logging granularity on Scripting objects and review activity daily until the patch is applied.
