The vulnerability exists because the affected software performs insufficient checks for associations between user accounts and organization accounts. An attacker who has administrator or compliance officer privileges for one organization account could exploit this vulnerability by using those privileges to view and modify data for another organization account. No customer data was impacted by this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","score":8.7},"cwes":["CWE-269","CWE-284"],"references":["http://www.securityfocus.com/bid/105301","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180905-webex-id-mod","http://www.securityfocus.com/bid/105301","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180905-webex-id-mod"],"products":["cisco:webex_teams"],"source":"nvd","synced_at":"2026-10-19T20:53:14.491561039+00:00"},"epss":{"cve":"CVE-2018-0436","score":0.01284,"percentile":0.70131,"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).
