CVE-2026-70687 Overview
CVE-2026-70687 is a high-severity vulnerability in the Oracle Marketing product of Oracle E-Business Suite, specifically within the Audience component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this vulnerability without user interaction. Successful exploitation results in unauthorized access to critical data or complete access to all Oracle Marketing accessible data. The vulnerability includes a scope change, meaning attacks may significantly impact additional products beyond Oracle Marketing itself.
Critical Impact
Attackers with low privileges can remotely access sensitive Oracle Marketing data and cause impacts extending beyond the vulnerable component due to scope change.
Affected Products
- Oracle E-Business Suite - Oracle Marketing (Audience component)
- Supported versions 12.2.3 through 12.2.15
- Deployments exposing Oracle Marketing over HTTP

Technical Details for CVE-2026-70687
Vulnerability Analysis
The vulnerability resides in the Audience component of Oracle Marketing, a module within the Oracle E-Business Suite (EBS) platform. Oracle EBS is a widely deployed enterprise application suite used for customer relationship management, marketing automation, and audience segmentation. The flaw is network-exploitable over HTTP and requires only low-level authenticated privileges. The scope change indicator signals that a successful exploit crosses trust boundaries, allowing the attacker to affect resources managed by components other than Oracle Marketing itself.
The impact is limited to confidentiality. Attackers cannot modify data or disrupt availability, but they can retrieve information ranging from sensitive marketing datasets to data managed by other in-scope Oracle EBS components. The EPSS score is 0.355% with a percentile of 28.84, indicating a moderate probability of exploitation activity relative to other published CVEs.
Root Cause
Oracle has not published detailed root-cause information beyond the Oracle Security Alert. The advisory describes the issue as an information disclosure weakness in the Audience component, allowing authenticated HTTP requests to access data beyond the requester's authorization boundary.
Attack Vector
The attack requires network access to the Oracle Marketing HTTP interface and valid low-privileged credentials to the Oracle E-Business Suite environment. No user interaction is required. The attacker issues crafted HTTP requests to the Audience component to retrieve data that should not be accessible under normal authorization checks. Because the vulnerability carries a scope change, the impact extends beyond Oracle Marketing to data or components managed under a different security authority.
No public proof-of-concept exploit is available for CVE-2026-70687 at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Oracle Security Alert for vendor guidance on technical characteristics.
Detection Methods for CVE-2026-70687
Indicators of Compromise
- Anomalous HTTP requests targeting Oracle Marketing Audience endpoints from low-privileged user accounts
- Unexpected volume of read operations against Oracle Marketing data by non-marketing user roles
- HTTP response payloads containing audience or campaign data returned to users lacking marketing-role assignments
Detection Strategies
- Review Oracle E-Business Suite audit logs for authenticated sessions accessing Audience component URLs outside normal business hours or from atypical source addresses
- Correlate application-tier HTTP logs with database access logs to identify unauthorized data reads originating from the Audience module
- Baseline typical Audience component usage patterns per user role and alert on deviations
Monitoring Recommendations
- Enable full HTTP request logging on Oracle EBS application servers hosting the Marketing module
- Forward Oracle EBS audit and access logs to a centralized SIEM for cross-source correlation and long-term retention
- Monitor authentication events for low-privileged accounts issuing unusual API calls to Marketing endpoints
How to Mitigate CVE-2026-70687
Immediate Actions Required
- Apply the Oracle security patch referenced in the Oracle Security Alert to all affected Oracle EBS deployments running versions 12.2.3 through 12.2.15
- Inventory all Oracle E-Business Suite instances and confirm the Oracle Marketing module and Audience component status
- Review and restrict low-privileged accounts that have HTTP access to the Oracle Marketing application tier
Patch Information
Oracle released a security patch as part of its August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for patch identifiers, prerequisite fixes, and installation instructions specific to their Oracle EBS release level.
Workarounds
- Restrict network access to the Oracle Marketing HTTP interface using firewall rules or reverse proxy allowlists until the patch is applied
- Disable or restrict access to the Audience component for user roles that do not require it
- Enforce least-privilege review across Oracle EBS accounts to reduce the pool of accounts capable of exploiting the flaw
