CVE-2026-61204 Overview
CVE-2026-61204 is a privilege management vulnerability in the Oracle PeopleSoft Enterprise FIN Program Management product, specifically within the Primavera Integration component. The affected supported version is 9.2. A low-privileged attacker with network access over HTTP can exploit the flaw to compromise PeopleSoft Enterprise FIN Program Management. Successful exploitation requires human interaction from a user other than the attacker and results in a scope change, meaning attacks can significantly impact additional products beyond the vulnerable component. The weakness is categorized under [CWE-269: Improper Privilege Management].
Critical Impact
Successful attacks can result in full takeover of PeopleSoft Enterprise FIN Program Management with high impacts to confidentiality, integrity, and availability, and may extend to additional integrated products.
Affected Products
- Oracle PeopleSoft Enterprise FIN Program Management version 9.2
- Component: Primavera Integration
- Related PeopleSoft deployments integrated with Primavera

Technical Details for CVE-2026-61204
Vulnerability Analysis
The vulnerability resides in the Primavera Integration component of PeopleSoft Enterprise FIN Program Management 9.2. An authenticated attacker with low privileges can send crafted HTTP requests to trigger the flaw. Exploitation requires a separate user to perform an action, such as clicking a link or visiting a page rendered by the application. Once triggered, the attacker can escalate privileges and take control of the FIN Program Management module.
The scope change indicates the vulnerable component and the impacted component are managed by different security authorities. Consequences therefore extend beyond PeopleSoft Enterprise FIN Program Management and can affect connected Primavera integrations and downstream systems. Oracle rates all three impact metrics (confidentiality, integrity, availability) as high.
Root Cause
The root cause is improper privilege management [CWE-269] within the Primavera Integration workflow. Application logic fails to correctly enforce authorization boundaries between low-privileged accounts and privileged operations reachable through the integration surface. This allows a low-privileged user to influence actions that should be restricted to higher-privileged principals.
Attack Vector
The attack vector is network-based over HTTP. An attacker authenticates with low privileges, then delivers a crafted request or link to a legitimate user of the PeopleSoft application. When the victim interacts with the attacker-controlled content, the request executes in the victim's authenticated session. This chained interaction enables the privilege escalation and cross-scope impact described in the advisory.
No public proof-of-concept exploit or exploitation in the wild has been reported at the time of publication. Refer to the Oracle Critical Patch Update July 2026 for vendor-supplied technical details.
Detection Methods for CVE-2026-61204
Indicators of Compromise
- Unexpected HTTP requests to Primavera Integration endpoints originating from low-privileged PeopleSoft user sessions.
- PeopleSoft audit log entries showing privilege changes, role assignments, or configuration edits performed under user accounts that lack administrative rights.
- Outbound requests from PeopleSoft servers to unfamiliar external hosts shortly after user interaction with emailed or chat-delivered links.
Detection Strategies
- Correlate PeopleSoft application logs with web server access logs to surface low-privileged sessions issuing privileged Primavera Integration operations.
- Baseline normal Primavera Integration traffic patterns and alert on deviations in request volume, endpoints, or parameters.
- Monitor for session activity that combines a user interaction event with an immediate sensitive administrative action.
Monitoring Recommendations
- Enable verbose auditing on PeopleSoft FIN Program Management, particularly for role changes and integration configuration updates.
- Forward web, application, and database logs to a centralized analytics platform for cross-source correlation.
- Track authentication events for accounts that interact with Primavera Integration endpoints and alert on privilege changes tied to those accounts.
How to Mitigate CVE-2026-61204
Immediate Actions Required
- Apply the fixes published in the Oracle Critical Patch Update July 2026 to all instances of PeopleSoft Enterprise FIN Program Management 9.2.
- Inventory PeopleSoft deployments and identify systems using the Primavera Integration component.
- Review recent PeopleSoft audit logs for suspicious privilege changes or administrative actions performed by low-privileged users.
- Restrict network access to PeopleSoft HTTP endpoints so only authorized users and networks can reach them.
Patch Information
Oracle addressed CVE-2026-61204 in the July 2026 Critical Patch Update. Administrators should download and install the patches specific to PeopleSoft Enterprise FIN Program Management 9.2 from My Oracle Support. Consult the Oracle Critical Patch Update July 2026 advisory for the complete patch matrix and prerequisites.
Workarounds
- Limit access to the Primavera Integration component to a minimal set of trusted users until patching is complete.
- Enforce least privilege by reviewing PeopleSoft roles and removing unnecessary permissions from low-privileged accounts.
- Deploy web application firewall rules to inspect and constrain requests to Primavera Integration URLs.
- Educate PeopleSoft users on the risk of clicking untrusted links, since exploitation requires victim interaction.
