A low-privileged local attacker can connect to this pipe and send crafted IPC messages to trigger execution of arbitrary commands with SYSTEM privileges via an untrusted search path. This allows privilege escalation by placing a malicious shadow.exe in a controlled working directory.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-276","CWE-426"],"references":["https://docs.matrix42.com/1041748_vulnerability-list/3862631_cve-2026-57919-privilege-escalation-in-empirum-personal-backup/","https://docs.matrix42.com/en_US/1041748_vulnerability-list/cve-2026-57919-privilege-escalation-in-empirum-personal-backup","https://matrix42.com"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-57919","score":0.00177,"percentile":0.07224,"date":"2026-11-01"},"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).
