An attacker could exploit this vulnerability by sending a crafted message to an affected Cisco SSM On-Prem host and retrieving session credentials from subsequent status messages. A successful exploit could allow the attacker to elevate privileges on the affected system from low to administrative.\r\nTo exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of System User.\r\nNote: This vulnerability exposes information only about users who logged in to the Cisco SSM On-Prem host using the web interface and who are currently logged in. SSH sessions are not affected.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","score":7.3},"cwes":["CWE-201"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cssm-priv-esc-xRAnOuO8"],"products":["cisco:smart_software_manager_on-prem"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-20151","score":0.0027,"percentile":0.19081,"date":"2026-10-26"},"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).
