CVE-2026-70820 Overview
CVE-2026-70820 affects the Oracle Call Center Technology product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are affected. The vulnerability allows a high-privileged attacker with network access via HTTP to compromise the Oracle Call Center Technology product. Successful exploitation can result in full takeover of Oracle Call Center Technology, impacting confidentiality, integrity, and availability.
Critical Impact
Successful exploitation grants a high-privileged, network-based attacker complete takeover of Oracle Call Center Technology, exposing all data and business processes handled by the application.
Affected Products
- Oracle E-Business Suite — Oracle Call Center Technology version 12.2.3
- Oracle E-Business Suite — Oracle Call Center Technology versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle Call Center Technology version 12.2.15

Technical Details for CVE-2026-70820
Vulnerability Analysis
The flaw resides in the Internal Operations component of Oracle Call Center Technology, a module of Oracle E-Business Suite used for managing call center workflows and agent operations. An attacker who already holds high privileges within the application can send crafted HTTP requests to trigger the vulnerability. Successful exploitation leads to complete takeover of the Call Center Technology product, with impact to confidentiality, integrity, and availability of the affected system.
Because Oracle Call Center Technology integrates with adjacent E-Business Suite modules such as Telesales, Marketing, and Service, a takeover of this component may extend attacker reach into linked business processes, customer records, and operational data.
Root Cause
Oracle's advisory identifies the affected component as Internal Operations without publishing a specific CWE classification. Oracle Critical Patch Update advisories intentionally omit low-level technical detail to limit exploitation risk prior to broad patch deployment. Refer to the Oracle Security Alert for authoritative version and component information.
Attack Vector
Exploitation requires network access to the HTTP interface of the affected Oracle E-Business Suite deployment. User interaction is not required, and the scope is unchanged. The attacker must already possess high privileges in the application, which reduces the pool of viable adversaries to authenticated users with elevated roles, compromised service accounts, or attackers who have chained a prior privilege escalation.
Detailed proof-of-concept exploitation code is not publicly available. See the Oracle Security Alert for vendor guidance.
Detection Methods for CVE-2026-70820
Indicators of Compromise
- Unexpected administrative or configuration changes within the Oracle Call Center Technology module.
- Anomalous HTTP requests targeting Internal Operations endpoints from authenticated high-privilege accounts.
- New or modified database objects owned by Call Center Technology schemas outside of scheduled change windows.
Detection Strategies
- Correlate application audit logs from Oracle E-Business Suite with web server access logs to identify abnormal request patterns from privileged users.
- Baseline normal activity for accounts with elevated Call Center Technology responsibilities and alert on deviations in request volume, source IP, or user-agent.
- Monitor for enumeration or reconnaissance attempts against E-Business Suite HTTP endpoints following the disclosure date.
Monitoring Recommendations
- Enable and centralize Oracle E-Business Suite FND_LOG_MESSAGES and sign-on audit logs for downstream analysis.
- Ingest HTTP access logs from the E-Business Suite application tier into a SIEM for query and retention.
- Alert on privileged account logins outside of business hours or from unexpected network segments.
How to Mitigate CVE-2026-70820
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to all affected Oracle E-Business Suite 12.2.3 through 12.2.15 instances.
- Inventory all E-Business Suite deployments running Oracle Call Center Technology and confirm patch status against the Oracle advisory.
- Review and reduce the number of accounts holding high-privilege responsibilities within Call Center Technology.
Patch Information
Oracle published fixes as part of its August 2026 Critical Patch Update. Consult the Oracle Security Alert for precise patch identifiers, prerequisites, and application instructions for each affected 12.2.x version.
Workarounds
- Restrict HTTP access to Oracle E-Business Suite application tiers using network segmentation and allow-lists until patches are applied.
- Enforce multi-factor authentication for all privileged E-Business Suite accounts to reduce the risk of credential compromise leading to exploitation.
- Audit and revoke unnecessary high-privilege responsibilities associated with Oracle Call Center Technology.
