CVE-2026-61012: Oracle Time and Labor Privilege Escalation

CVE-2026-61012 Overview

CVE-2026-61012 affects the Internal Operations component of Oracle Time and Labor, part of Oracle E-Business Suite. The flaw allows a low-privileged attacker with network access over HTTP to compromise the application without user interaction. Successful exploitation grants unauthorized create, delete, or modify access to all data accessible to Oracle Time and Labor. Attackers can also cause a partial denial of service against the product. Oracle disclosed the issue in the Oracle Critical Patch Update July 2026.

Critical Impact
An authenticated remote attacker can tamper with or destroy Oracle Time and Labor data and degrade service availability across supported deployments.

Affected Products

Oracle E-Business Suite — Oracle Time and Labor, versions 12.2.3 through 12.2.15
Component: Internal Operations
Deployments exposing Oracle E-Business Suite HTTP endpoints to authenticated users

Technical Details for CVE-2026-61012

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Time and Labor within Oracle E-Business Suite. An attacker requires only low privileges and network reachability to the HTTP interface. No user interaction is needed to trigger the flaw. Oracle categorizes the impact as high to integrity and low to availability, with no confidentiality impact.

The integrity impact allows unauthorized creation, deletion, or modification of any data the Oracle Time and Labor application can reach. This includes time entries, labor allocations, and related operational records. The availability impact manifests as a partial denial of service that degrades the Oracle Time and Labor application without necessarily affecting other Oracle E-Business Suite modules. The EPSS score at publication is 0.354% (percentile 27.862).

Root Cause

Oracle has not published detailed root cause information beyond the advisory. The advisory identifies the Internal Operations component as the affected surface. The requirement for low privileges combined with HTTP-based exploitation is consistent with insufficient authorization enforcement on server-side operations exposed to authenticated users.

Attack Vector

The attack vector is network-based over HTTP. An attacker authenticates to the Oracle E-Business Suite application with any low-privileged account. The attacker then issues crafted requests to the Internal Operations component of Oracle Time and Labor. Because the scope is unchanged, the impact remains confined to the vulnerable component. Refer to the Oracle Critical Patch Update July 2026 for technical guidance from the vendor.

Detection Methods for CVE-2026-61012

Indicators of Compromise

Unexpected modification, insertion, or deletion of records in Oracle Time and Labor tables performed by low-privileged accounts.
HTTP requests from authenticated sessions targeting Internal Operations endpoints outside documented business workflows.
Application-layer errors or timeouts in Oracle Time and Labor consistent with partial denial of service.

Detection Strategies

Correlate Oracle E-Business Suite application logs with database audit records to identify unauthorized write operations attributable to Time and Labor sessions.
Baseline normal request volume and endpoint distribution for Oracle Time and Labor, then alert on deviations from authenticated but non-privileged sessions.
Enable Oracle E-Business Suite Sign-On Audit and FND user activity logging to attribute suspicious operations to specific user accounts.

Monitoring Recommendations

Forward Oracle E-Business Suite application server, database audit, and web tier access logs to a centralized analytics platform for cross-source correlation.
Alert on integrity-relevant DML operations against Time and Labor schemas executed outside approved change windows.
Track authentication anomalies such as new low-privileged accounts accessing Internal Operations endpoints for the first time.

How to Mitigate CVE-2026-61012

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running Oracle Time and Labor versions 12.2.3 through 12.2.15.
Inventory all low-privileged accounts with network access to Oracle Time and Labor and remove those no longer required.
Review recent Oracle Time and Labor data changes for unauthorized modifications made prior to patching.

Patch Information

Oracle addressed CVE-2026-61012 in the Oracle Critical Patch Update released in July 2026. Customers should download and apply the vendor patch documented in the Oracle Critical Patch Update July 2026 advisory. Test the patch in a non-production environment before rolling it out to production Oracle E-Business Suite instances.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints using firewall rules, VPN, or reverse proxy allowlists until patches are applied.
Disable or limit access to the Oracle Time and Labor module for user populations that do not require it.
Increase database and application-layer auditing on Time and Labor objects to detect exploitation attempts during the patch window.
