Lifecycle Timeline
1DescriptionCVE.org
Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Security). Supported versions that are affected are 8.61 and 8.62. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PeopleTools, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise PeopleTools accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PeopleTools accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).
AnalysisAI
Cross-user attack in Oracle PeopleSoft Enterprise PeopleTools 8.61 and 8.62 enables a low-privileged network attacker to compromise confidentiality and integrity of data across component boundaries when a victim user interacts with attacker-controlled content. The Security component is the attack surface, consistent with stored or reflected client-side injection (e.g., XSS) that hijacks session or data context of another user. No public exploit identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Technical ContextAI
Oracle PeopleSoft Enterprise PeopleTools is the underlying development and runtime framework for PeopleSoft applications (HCM, ERP, Campus Solutions). The affected component is 'Security', which handles authentication, authorization, and session management. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C) is characteristic of a cross-site scripting or client-side injection class vulnerability: a low-privileged authenticated attacker injects malicious content that executes in the browser context of another user, causing a scope change that can impact components or data accessible to the victim. The 'Authentication Bypass' tag in the intelligence data may indicate the attack achieves privilege escalation or bypasses authorization checks indirectly through the victim's session, rather than bypassing the authentication mechanism entirely. CWE classification was not provided by the reporter.
RemediationAI
Apply the Oracle Critical Patch Update for July 2026, which addresses this vulnerability in PeopleSoft Enterprise PeopleTools 8.61 and 8.62. The advisory is available at https://www.oracle.com/security-alerts/cpujul2026.html. An exact patched version number was not independently confirmed beyond the CPU advisory reference - consult Oracle MOS (My Oracle Support) for the specific PeopleTools patch ID and verify patch applicability against your environment's patch level. If immediate patching is not feasible, consider restricting access to the PeopleSoft Security component to trusted internal network segments to reduce exposure (trade-off: limits remote HR/admin access). Additionally, enforce strict Content Security Policy (CSP) headers on the PeopleSoft web tier to mitigate client-side injection vectors - this requires PeopleTools web server configuration and may affect rich UI functionality.
