CVE-2026-61056 Overview
CVE-2026-61056 is a vulnerability in the Oracle PeopleSoft Enterprise FIN Grants product, specifically within the Grants component. The affected supported version is 9.2. An unauthenticated attacker with network access via HTTP can exploit this flaw, though successful exploitation requires overcoming high attack complexity.
Successful attacks can result in unauthorized update, insert, or delete access to a subset of PeopleSoft Enterprise FIN Grants data. Attackers can also gain unauthorized read access to a subset of accessible data. Oracle disclosed the vulnerability as part of the July 2026 Critical Patch Update.
Critical Impact
Unauthenticated network-based attackers can modify and read a subset of PeopleSoft FIN Grants data, affecting confidentiality and integrity of grant management records.
Affected Products
- Oracle PeopleSoft Enterprise FIN Grants 9.2
- Grants component
- Oracle PeopleSoft product family

Technical Details for CVE-2026-61056
Vulnerability Analysis
The vulnerability resides in the Grants component of Oracle PeopleSoft Enterprise FIN Grants version 9.2. Oracle classifies the flaw as difficult to exploit, meaning attackers must satisfy specific preconditions or race conditions outside their direct control. Despite the high complexity, the vulnerability requires no authentication and no user interaction.
Exploitation occurs over the network via HTTP, indicating the flaw is accessible through the standard PeopleSoft web tier. Successful attacks impact both confidentiality and integrity at a limited scope. Availability is not affected, and the scope remains unchanged, meaning the compromise is contained within the vulnerable component.
Oracle's advisory does not disclose a specific weakness classification (CWE) for this issue. The impact profile — partial read plus partial write to grants data — is consistent with input validation or access control flaws affecting a subset of PeopleSoft Grants records.
Root Cause
Oracle has not published detailed root cause information. The advisory indicates the flaw is inside the Grants component of the FIN Grants module. Based on the impact vector, the underlying weakness likely involves improper access control or input validation on HTTP-exposed Grants functionality.
Attack Vector
An attacker sends crafted HTTP requests to the PeopleSoft Enterprise FIN Grants web-facing interface. No credentials or user interaction are required. Because attack complexity is high, exploitation depends on non-trivial conditions such as timing, configuration state, or specific data prerequisites.
No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported. The EPSS score is 0.22%, reflecting a low near-term likelihood of exploitation.

Detection Methods for CVE-2026-61056
Indicators of Compromise
- Unexpected INSERT, UPDATE, or DELETE operations against PeopleSoft Grants tables from unauthenticated web sessions
- Anomalous HTTP requests to Grants component endpoints originating from external IP addresses
- Audit log entries showing data modifications without a corresponding authenticated user context
Detection Strategies
- Enable and review PeopleSoft application audit logging for Grants component transactions
- Correlate web server access logs with database change events to identify unauthenticated data modifications
- Deploy web application firewall rules to inspect HTTP requests targeting FIN Grants endpoints for anomalous parameters
Monitoring Recommendations
- Monitor PeopleSoft web tier logs for request patterns targeting the Grants component outside normal business workflows
- Alert on database changes to grants records that lack an associated authenticated session ID
- Track outbound authentication events and compare against Grants data change timestamps
How to Mitigate CVE-2026-61056
Immediate Actions Required
- Apply the Oracle July 2026 Critical Patch Update for PeopleSoft Enterprise FIN Grants 9.2
- Inventory all PeopleSoft FIN Grants deployments and confirm patch status
- Restrict network exposure of the PeopleSoft web tier to trusted networks where feasible
- Review Grants component audit trails for suspicious activity prior to patching
Patch Information
Oracle addressed CVE-2026-61056 in the July 2026 Critical Patch Update. Administrators should apply the fixes documented in the Oracle Critical Patch Update Advisory - July 2026. Oracle strongly recommends applying Critical Patch Update fixes without delay for all supported product versions.
Workarounds
- Place the PeopleSoft web tier behind a reverse proxy or WAF that enforces strict request validation for Grants endpoints
- Limit HTTP access to the FIN Grants interface using network-level access control lists
- Increase audit logging verbosity on the Grants component until patching is complete
