An unauthenticated attacker can send specially crafted HTTP requests to a publicly exposed interface, which may allow them to perform unauthorized updates, inserts, or deletes on database records, and to read a subset of data that should otherwise be protected. Although the description does not explicitly describe the issue as an XSS flaw, the cited CWE\u201179 and the nature of the traffic imply a cross\u2011site scripting style weakness that is exploitable without authentication.", "risk_and_exploitability": "The CVSS 3.1 base score of 6.1 reflects moderate severity, with limited impact on confidentiality and integrity and no availability impact. The EPSS score is less than 1\u202f%, indicating a very low likelihood of exploitation in the wild, and the vulnerability is not listed in CISA\u2019s KEV catalog. Exploitation demands that an attacker send a malicious HTTP request and, because the attack requires a separate user to interact with the system, also depends on social\u2011engineering or human\u2011interaction tactics. The scope is potentially broader than PeopleSoft alone, as the breach may affect other integrated applications."}}}}, "created": "2026-04-18T15:45:04.273688+00:00", "title": "Unauthenticated HTTP Vulnerability in Oracle PeopleSoft Integration Broker Allows Unauthorized Data Modification and Disclosure", "updated": "2026-04-18T15:45:04.273699+00:00", "vendors": []}
