CVE-2026-61051 Overview
CVE-2026-61051 is a vulnerability in the Oracle Concurrent Processing product of Oracle E-Business Suite, specifically within the BI Publisher Integration component. Oracle addressed the issue in the July 2026 Critical Patch Update. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit the weakness to compromise Oracle Concurrent Processing. Successful exploitation allows unauthorized update, insert, or delete operations against a subset of accessible data, unauthorized read access to a subset of data, and a partial denial of service condition.
Critical Impact
Authenticated network attackers can tamper with Oracle Concurrent Processing data and trigger partial denial of service against affected E-Business Suite deployments.
Affected Products
- Oracle E-Business Suite — Oracle Concurrent Processing (BI Publisher Integration)
- Supported versions 12.2.3 through 12.2.15
- Deployments exposing Concurrent Processing endpoints over HTTP to authenticated users

Technical Details for CVE-2026-61051
Vulnerability Analysis
The vulnerability resides in the BI Publisher Integration component of Oracle Concurrent Processing within Oracle E-Business Suite. Oracle classifies the flaw as easily exploitable by a low-privileged attacker with network access over HTTP. The scope remains unchanged, and the impacts affect confidentiality, integrity, and availability at a limited level.
Successful exploitation grants an attacker unauthorized update, insert, or delete access to a subset of Concurrent Processing data. It also permits unauthorized read access to a subset of accessible data and can cause a partial denial of service against the Concurrent Processing service. The EPSS probability at publication is 0.272%.
Root Cause
Oracle has not published detailed root-cause information beyond identifying the affected component. The advisory attributes the issue to the BI Publisher Integration surface exposed through Oracle Concurrent Processing. Because the attack requires only low privileges and no user interaction, the underlying weakness likely stems from insufficient authorization enforcement on integration endpoints reachable by authenticated users.
Attack Vector
Exploitation occurs remotely over HTTP against the Oracle E-Business Suite application tier. The attacker must possess valid low-privilege credentials for the target environment. No user interaction is required. Because access complexity is low, an attacker with authenticated session tokens can direct crafted requests at the BI Publisher Integration endpoints of Concurrent Processing to achieve partial data manipulation, disclosure, and service disruption.
Refer to the Oracle Security Alert July 2026 for vendor-provided technical context.
Detection Methods for CVE-2026-61051
Indicators of Compromise
- Unexpected HTTP requests from low-privileged user sessions targeting BI Publisher Integration URLs within Oracle Concurrent Processing.
- Unauthorized modifications, insertions, or deletions in Concurrent Processing tables that cannot be tied to legitimate business workflows.
- Intermittent unavailability or degraded response times for Concurrent Processing requests aligned with anomalous HTTP activity.
Detection Strategies
- Review Oracle E-Business Suite application access logs for anomalous invocations of BI Publisher Integration endpoints by non-administrative accounts.
- Correlate database audit records with application session identifiers to spot data changes originating from unexpected user contexts.
- Baseline typical Concurrent Processing request volumes and flag deviations that coincide with denial-of-service symptoms.
Monitoring Recommendations
- Enable Oracle E-Business Suite Sign-On Audit and application tier access logging with retention sufficient for forensic review.
- Forward web tier, application, and database audit logs to a centralized analytics platform for cross-source correlation.
- Alert on repeated failed authorization events against BI Publisher Integration URLs and on spikes in Concurrent Processing errors.
How to Mitigate CVE-2026-61051
Immediate Actions Required
- Apply the fixes from the Oracle Security Alert July 2026 to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
- Inventory environments to confirm the Concurrent Processing and BI Publisher Integration components are patched consistently across production, test, and disaster-recovery tiers.
- Rotate credentials for low-privileged application accounts that may have been exposed if suspicious activity is observed.
Patch Information
Oracle released the patch as part of the July 2026 Critical Patch Update cycle. Administrators should follow the Oracle Security Alert July 2026 advisory to identify the correct patch bundle for their Oracle E-Business Suite 12.2.x release and apply it through the standard AD administration utilities.
Workarounds
- Restrict network access to Oracle E-Business Suite application tier endpoints so that only trusted internal networks can reach BI Publisher Integration URLs.
- Enforce least-privilege on Oracle E-Business Suite responsibilities so that low-privileged accounts cannot reach Concurrent Processing functions unnecessarily.
- Increase auditing on Concurrent Processing activity until patching is completed to shorten detection time for exploitation attempts.
