Summary
CVE-2026-61088 is a high-severity improper access control vulnerability (CWE-284) affecting Oracle PeopleSoft Enterprise SCM Manufacturing version 9.2, disclosed as part of Oracle’s July 2026 Critical Patch Update (CPU) on July 21, 2026. An unauthenticated, remote attacker with network access via HTTP can exploit this flaw to gain unauthorized read access to critical manufacturing and supply chain data. The vulnerability carries a CVSS v3.1 base score of 7.5 (HIGH).
Technical details
- Root cause: Improper access control (CWE-284) in the Security component of Oracle PeopleSoft Enterprise SCM Manufacturing, allowing requests to bypass authentication and authorization checks.
- Trigger conditions: The vulnerability is described by Oracle as "easily exploitable" — no authentication, no user interaction, and no special configuration is required to trigger it.
- Attack vector: Network-accessible via HTTP; an unauthenticated attacker can send crafted HTTP requests directly to an internet-exposed PeopleSoft instance.
- Impact: Successful exploitation grants an attacker unauthorized access to critical data, or complete read access to all data accessible within the PeopleSoft Enterprise SCM Manufacturing application. There is no impact on data integrity or system availability.
