The vulnerability is due to improper validation of input to API requests that are a part of meeting join flow. An attacker could exploit this vulnerability by sending an API request to the application, which would return a URL that includes a meeting join page that is prepopulated with the meeting username and password. A successful exploit could allow the attacker to join the password-protected meeting. The attacker would be visible in the attendee list of the meeting.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.3},"cwes":["CWE-20"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-meetings-UtbwOR4Q","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-meetings-UtbwOR4Q"],"products":["cisco:webex_training"],"source":"nvd","synced_at":"2026-10-19T21:09:20.498348299+00:00"},"epss":{"cve":"CVE-2020-3542","score":0.01079,"percentile":0.6508,"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).
