CVE-2026-60919 Overview
CVE-2026-60919 affects the Oracle iSupplier Portal component of Oracle E-Business Suite, specifically the Internal Operations subcomponent. Supported versions 12.2.3 through 12.2.15 are impacted. The vulnerability allows an unauthenticated attacker with network access via HTTP to compromise Oracle iSupplier Portal. Successful exploitation results in unauthorized read access to a subset of Oracle iSupplier Portal accessible data. Oracle documented the flaw in the July 2026 Critical Patch Update. The issue is classified as difficult to exploit and is scoped to confidentiality impact only.
Critical Impact
Unauthenticated remote attackers can read a subset of iSupplier Portal data over HTTP without user interaction, though exploitation complexity is high.
Affected Products
- Oracle E-Business Suite - Oracle iSupplier Portal 12.2.3 through 12.2.15
- Component: Internal Operations
- Attack surface: HTTP-accessible iSupplier Portal endpoints

Technical Details for CVE-2026-60919
Vulnerability Analysis
CVE-2026-60919 is an information disclosure vulnerability in the Internal Operations component of Oracle iSupplier Portal. An unauthenticated attacker can send crafted HTTP requests to the iSupplier Portal and retrieve a subset of accessible data. Oracle classifies the attack complexity as high, indicating that exploitation depends on conditions outside the attacker's direct control. The vulnerability does not affect integrity or availability. Because iSupplier Portal is often exposed to third-party suppliers over the internet, network reachability is a realistic precondition for many deployments. Oracle has not published detailed technical information about the underlying defect. Refer to the Oracle Security Alert July 2026 for the authoritative advisory.
Root Cause
Oracle has not disclosed the root cause. The advisory indicates an information exposure condition reachable through HTTP requests against the Internal Operations subcomponent of iSupplier Portal. No CWE classification has been assigned in NVD at the time of publication.
Attack Vector
The attack vector is network-based over HTTP. No authentication is required and no user interaction is needed. The attacker must overcome conditions that make exploitation difficult, which Oracle reflects in the high attack complexity rating. Successful requests return unauthorized read access to a limited subset of iSupplier Portal data.
No verified public proof-of-concept code is available. See the Oracle Security Alert July 2026 for vendor-supplied technical context.
Detection Methods for CVE-2026-60919
Indicators of Compromise
- Anomalous unauthenticated HTTP requests to Oracle iSupplier Portal endpoints, particularly those associated with Internal Operations pages
- Repeated HTTP GET requests from a single external source enumerating iSupplier Portal URLs
- Unusual response sizes or bursts of 200 OK responses to unauthenticated requests against portal resources
Detection Strategies
- Review Oracle E-Business Suite HTTP access logs for unauthenticated requests reaching iSupplier Portal pages under the Internal Operations component
- Correlate web application firewall (WAF) events with iSupplier Portal request patterns to identify probing activity
- Baseline typical supplier traffic and alert on deviations in source geography, user agents, and request volume
Monitoring Recommendations
- Forward Oracle HTTP Server and application server logs to a centralized analytics platform for retention and query
- Enable verbose audit logging on iSupplier Portal to capture request URIs, source IPs, and response codes
- Track patch state of Oracle E-Business Suite instances against the July 2026 Critical Patch Update baseline
How to Mitigate CVE-2026-60919
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update for Oracle E-Business Suite to all affected versions between 12.2.3 and 12.2.15
- Inventory internet-exposed iSupplier Portal instances and prioritize them for patching
- Restrict inbound HTTP access to iSupplier Portal to known supplier networks where operationally feasible
Patch Information
Oracle addressed CVE-2026-60919 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 and apply the patches referenced for Oracle E-Business Suite iSupplier Portal versions 12.2.3 through 12.2.15.
Workarounds
- Place iSupplier Portal behind a reverse proxy or WAF that enforces authentication and rate limiting on Internal Operations paths
- Apply network access control lists to limit HTTP reachability to trusted supplier IP ranges
- Increase logging and alerting on unauthenticated request patterns until the patch is deployed
# Example: restrict inbound HTTP access to iSupplier Portal at the network edge
# Replace <supplier_cidr> with authorized supplier network ranges
iptables -A INPUT -p tcp --dport 443 -s <supplier_cidr> -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
