{"id":"CVE-2026-101426","kind":"vulnerability","aliases":["CVE-2026-101426"],"related":[],"title":"Oracle PeopleSoft PeopleTools: SQR flaw lets insider alter data or crash service","description":"Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: SQR).  Supported versions that are affected are 8.61-8.63. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where PeopleSoft Enterprise PeopleTools executes 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 creation, deletion or modification access to critical data or all PeopleSoft Enterprise PeopleTools accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of PeopleSoft Enterprise PeopleTools. CVSS 3.1 Base Score 6.9 (Integrity and Availability impacts).
