The portal component is delivered with an insecure default User Profile community configuration that allows anonymous users to retrieve the account names of all portal users via /portal/server.pt/user/user/ requests. When WCI is synchronised with Active Directory (AD), this vulnerability can expose the account names of all AD users. NOTE: this CVE is assigned by MITRE and isn't validated by Oracle because Oracle WebCenter Interaction Portal is out of support.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["http://www.securityfocus.com/bid/105350","https://seclists.org/fulldisclosure/2018/Sep/22","http://www.securityfocus.com/bid/105350","https://seclists.org/fulldisclosure/2018/Sep/22"],"products":["oracle:webcenter_interaction"],"source":"nvd","synced_at":"2026-10-19T20:53:14.491561039+00:00"},"epss":{"cve":"CVE-2018-16959","score":0.0124,"percentile":0.69163,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
