CVE-2026-60893 Overview
CVE-2026-60893 affects the Oracle Payroll product within Oracle E-Business Suite, specifically the Internal Operations component. The flaw impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with logon access to the infrastructure running Oracle Payroll can exploit this issue without user interaction. Successful exploitation yields unauthorized access to critical data or complete access to all Oracle Payroll accessible data. The scope change indicates that impact extends beyond Oracle Payroll to additional Oracle E-Business Suite products.
Critical Impact
Local, low-privileged attackers can compromise confidentiality across Oracle Payroll and connected E-Business Suite components through a scope-changing information disclosure flaw.
Affected Products
- Oracle E-Business Suite — Oracle Payroll version 12.2.3
- Oracle E-Business Suite — Oracle Payroll versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle Payroll version 12.2.15

Technical Details for CVE-2026-60893
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle Payroll. An authenticated attacker who can log on to the infrastructure hosting Oracle Payroll can leverage the flaw to read sensitive data stored or processed by the Payroll module. The confidentiality impact is high, while integrity and availability are unaffected. The scope change is significant. It means the vulnerable component and the impacted component differ in authority, allowing the attacker to reach data belonging to other Oracle E-Business Suite components that share the runtime environment.
Oracle categorizes the issue as easily exploitable. The attack complexity is low, no user interaction is required, and only low-level credentials on the underlying infrastructure are needed. This profile makes the flaw attractive for insiders, contractors, and any adversary who has already achieved a foothold on the application host.
Root Cause
Oracle has not published a detailed root-cause analysis. Based on the advisory, the defect stems from insufficient access controls within Internal Operations handling, which permits a local, authenticated principal to retrieve payroll data outside its authorized boundary. Refer to the Oracle Security Alert July 2026 for vendor-supplied technical guidance.
Attack Vector
The attack vector is Local. Exploitation requires the attacker to authenticate to the operating system or middleware layer where Oracle Payroll executes. From that context, the attacker interacts with Internal Operations interfaces to read data belonging to Oracle Payroll and, due to the scope change, other resources reachable from that runtime. No network-facing exploitation primitive is documented, and no public proof-of-concept is currently available.
Detection Methods for CVE-2026-60893
Indicators of Compromise
- Unexpected interactive or programmatic logons to hosts running Oracle E-Business Suite from accounts that do not typically administer Payroll.
- Anomalous read access patterns against Payroll schema objects, especially bulk queries executed by low-privileged OS accounts.
- Execution of Internal Operations utilities or scripts outside of scheduled maintenance windows.
Detection Strategies
- Enable Oracle Database Fine-Grained Auditing on Payroll tables to record SELECT activity by non-application accounts.
- Correlate operating system logon events on E-Business Suite tiers with subsequent database sessions to identify lateral access.
- Baseline normal APPLMGR and application-tier service behavior and alert on deviations that touch Payroll data.
Monitoring Recommendations
- Forward Oracle E-Business Suite concurrent manager logs, database audit logs, and host authentication logs to a centralized analytics platform.
- Alert on new local accounts or group memberships added on E-Business Suite application tiers.
- Monitor for use of the sqlplus, adadmin, and adctrl utilities by unexpected principals.
How to Mitigate CVE-2026-60893
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update to all Oracle Payroll instances running versions 12.2.3 through 12.2.15.
- Inventory all hosts running Oracle E-Business Suite and confirm patch status against the Oracle Security Alert July 2026.
- Review and reduce interactive logon rights on Oracle Payroll application and database tiers to the minimum required set of administrators.
Patch Information
Oracle addressed CVE-2026-60893 in the Critical Patch Update released in July 2026. Administrators should consult the Oracle Critical Patch Update Advisory - July 2026 for the specific patch numbers applicable to Oracle E-Business Suite 12.2.x deployments and follow Oracle's documented apply procedure using adop.
Workarounds
- Restrict OS-level logon on Payroll infrastructure to a small, audited set of administrators using host-based access controls.
- Enforce multi-factor authentication for administrative access to Oracle E-Business Suite tiers to reduce the risk of low-privileged account misuse.
- Segment Oracle E-Business Suite hosts on isolated management networks and disallow shared tenancy with unrelated workloads until the patch is applied.
