Summary
CVE-2026-61089 is a high-severity improper access control vulnerability affecting Oracle PeopleSoft Enterprise SCM Inventory version 9.2. The flaw resides in the Security component and allows unauthenticated, remote attackers to gain unauthorized access to sensitive supply chain inventory data via HTTP, with no credentials or user interaction required. It was disclosed as part of Oracle’s July 2026 Critical Patch Update and carries a CVSS v3.1 base score of 8.2 (HIGH).
Technical details
- Root cause: Improper access control (CWE-284) in the Security component of Oracle PeopleSoft Enterprise SCM Inventory, permitting requests to bypass authentication and authorization checks.
- Trigger conditions: No authentication, no user interaction, and no special privileges are required — the vulnerability is exploitable by any network-accessible attacker.
- Attack vector: Network-based, exploitable remotely over HTTP. Attack complexity is low, making automated or mass exploitation feasible.
- Impact: Successful exploitation grants an unauthenticated attacker unauthorized read access to critical SCM Inventory data (High confidentiality impact), and limited unauthorized modification or deletion of accessible data (Low integrity impact). Availability is not affected.
