CVE-2026-60823 Overview
CVE-2026-60823 is a high-severity vulnerability in the Oracle iSupport product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access via HTTP can compromise Oracle iSupport, though the attack complexity is high. Successful exploitation allows unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all Oracle iSupport accessible data.
Critical Impact
Remote, unauthenticated attackers can achieve full read and write access to Oracle iSupport data, impacting both confidentiality and integrity of business-critical records.
Affected Products
- Oracle E-Business Suite — Oracle iSupport, version 12.2.3
- Oracle E-Business Suite — Oracle iSupport, versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle iSupport, version 12.2.15

Technical Details for CVE-2026-60823
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle iSupport, a self-service customer support module within Oracle E-Business Suite. The flaw is exposed over HTTP and does not require authentication or user interaction. Attack complexity is high, meaning exploitation depends on conditions outside the attacker's direct control, such as specific configuration states or timing.
Successful exploitation yields high confidentiality and integrity impact. Attackers can read, create, modify, or delete any data accessible to Oracle iSupport. Availability is not affected, indicating the flaw does not disable the service itself. The EPSS probability is 0.257% (17.262 percentile), reflecting a currently low predicted likelihood of exploitation activity.
Root Cause
Oracle has not publicly disclosed the underlying weakness class, and no CWE identifier is assigned. Based on the impact profile — unauthenticated remote data read and modification through HTTP against a business application module — the flaw is consistent with a broken access control or improper authorization defect in an internally exposed operations interface. See the Oracle Critical Patch Update July 2026 advisory for vendor-supplied details.
Attack Vector
The attacker requires only network reachability to the Oracle iSupport HTTP endpoint. No credentials, tokens, or user interaction are needed. Because Oracle iSupport is frequently deployed as an internet-facing self-service portal, exposed instances may be reachable directly from untrusted networks. The high attack complexity suggests exploitation requires precise request crafting or knowledge of internal identifiers, but does not require privilege of any kind.
No public proof-of-concept, exploit code, or CISA Known Exploited Vulnerabilities listing exists for CVE-2026-60823 at the time of publication.
Detection Methods for CVE-2026-60823
Indicators of Compromise
- Unexpected HTTP requests to Oracle iSupport Internal Operations endpoints from external or unusual source addresses.
- Unauthenticated sessions performing create, update, or delete operations against iSupport data objects.
- Anomalous record modifications in iSupport tables with no corresponding user session or audit trail entry.
Detection Strategies
- Enable Oracle E-Business Suite audit logging on iSupport data tables and monitor for write operations without an authenticated user context.
- Deploy web application firewall rules that inspect requests to Oracle iSupport URLs for unauthenticated access to internal operations paths.
- Correlate application logs with network flow data to identify direct HTTP calls that bypass the standard authentication workflow.
Monitoring Recommendations
- Alert on iSupport HTTP requests originating from source IPs outside expected customer or partner ranges.
- Baseline normal iSupport transaction volumes and flag deviations in record creation, deletion, or update rates.
- Forward Oracle E-Business Suite application, database, and web tier logs to a centralized SIEM for cross-layer correlation.
How to Mitigate CVE-2026-60823
Immediate Actions Required
- Apply the fixes provided in the Oracle Critical Patch Update July 2026 to all Oracle iSupport deployments running versions 12.2.3 through 12.2.15.
- Inventory all Oracle E-Business Suite instances and confirm which have Oracle iSupport enabled and exposed over HTTP or HTTPS.
- Restrict network access to Oracle iSupport endpoints to trusted networks until patching is complete.
Patch Information
Oracle addressed CVE-2026-60823 in the July 2026 Critical Patch Update. Administrators should review the advisory, identify the specific patch bundle for their Oracle E-Business Suite 12.2.x release, and follow Oracle's documented patch application procedure through Oracle Support. Post-patch validation should confirm the iSupport module version and functional testing of Internal Operations workflows.
Workarounds
- Place Oracle iSupport behind a reverse proxy or web application firewall that enforces authentication before requests reach the application.
- Disable the Oracle iSupport module in environments where it is not required for business operations.
- Restrict inbound HTTP access to the iSupport Internal Operations paths using network access control lists until the Oracle CPU is deployed.
