CVE-2026-62449: Oracle E-Business Suite Escalation Flaw

CVE-2026-62449 Overview

CVE-2026-62449 affects the Oracle Work in Process 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 low-privileged attacker with logon access to the infrastructure where Oracle Work in Process executes to compromise the application. Successful exploitation results in full takeover of Oracle Work in Process, with high impact to confidentiality, integrity, and availability. Oracle published the fix in its August 2026 Security Alert cycle.

Critical Impact
Successful exploitation results in complete takeover of Oracle Work in Process, exposing manufacturing data and disrupting production operations.

Technical Details for CVE-2026-62449

Vulnerability Analysis

CVE-2026-62449 resides in the Internal Operations component of Oracle Work in Process, a manufacturing execution module of Oracle E-Business Suite. Oracle classifies the issue as difficult to exploit and requiring local access with low privileges. No user interaction is required.

An attacker who successfully exploits the flaw achieves full takeover of the Work in Process application. This includes access to production schedules, bill-of-materials data, and job records, as well as the ability to alter or destroy manufacturing state. In production environments, tampering with Work in Process data can cascade into inventory, cost accounting, and shop-floor execution modules.

Oracle has not publicly disclosed the underlying weakness class. Based on the local attack vector and the privileges-required rating, the flaw is consistent with insecure privileged operations reachable by an authenticated application-tier user.

Root Cause

Oracle's security alert does not publish the root cause or CWE for CVE-2026-62449. The advisory describes the flaw as reachable only from the infrastructure where Oracle Work in Process executes, which points to a defect in a privileged internal code path rather than a network-facing interface. Consult the Oracle Security Alert for vendor-supplied details.

Attack Vector

Exploitation requires a local logon to the host or application-tier infrastructure running Oracle Work in Process. The attacker must already hold low-level privileges on that infrastructure. Once positioned, the attacker abuses the Internal Operations component to escalate control over the Work in Process product. Remote unauthenticated exploitation is not possible based on Oracle's advisory. No public proof-of-concept, exploit, or CISA KEV listing exists at the time of writing, and the EPSS probability sits at 0.131%.

No verified exploit code is publicly available. Refer to the Oracle Security Alert for technical details.

Detection Methods for CVE-2026-62449

Indicators of Compromise

Unexpected interactive or batch logons to Oracle E-Business Suite application-tier hosts by low-privileged accounts.
Anomalous invocations of Work in Process Internal Operations concurrent programs or PL/SQL packages outside normal maintenance windows.
Unauthorized modifications to Work in Process job, routing, or resource tables such as WIP_DISCRETE_JOBS, WIP_OPERATIONS, or WIP_ENTITIES.

Detection Strategies

Enable Oracle E-Business Suite auditing on Work in Process schemas and correlate database audit trails with OS-level logons on the application-tier hosts.
Baseline normal execution of Internal Operations components and alert on privilege changes, new database roles, or unexpected APPLSYS package modifications.
Compare Oracle patch inventory against the August 2026 Critical Patch Update to identify unpatched Work in Process instances.

Monitoring Recommendations

Forward Oracle EBS FND_LOG_MESSAGES, database audit logs, and host telemetry to a centralized SIEM for correlation and long-term retention.
Monitor for creation of new EBS responsibilities, menu grants, or database accounts on hosts running Work in Process.
Track file integrity on $APPL_TOP, $INST_TOP, and Work in Process form and library directories.

How to Mitigate CVE-2026-62449

Immediate Actions Required

Apply the Oracle August 2026 Security Alert patches for affected Oracle E-Business Suite 12.2.3 through 12.2.15 Work in Process instances.
Restrict interactive and SSH logon on Oracle E-Business Suite application-tier hosts to a minimum set of administrators.
Audit existing EBS accounts and OS accounts on the application tier and remove unused or over-privileged credentials.

Patch Information

Oracle addressed CVE-2026-62449 in the August 2026 Security Alert. Administrators should review the Oracle Security Alert for the applicable patch identifiers for Oracle Work in Process versions 12.2.3 through 12.2.15 and apply them following Oracle's standard EBS patching procedure using adop.

Workarounds

No vendor-supplied workaround is published. Apply the Oracle patch as the primary remediation.
Where patching must be delayed, tighten network and host access controls so that only trusted administrators can reach the application-tier infrastructure.
Enforce least privilege on EBS responsibilities associated with Work in Process Internal Operations until the patch is deployed.
