The files are deployed with those permissions, which would let a local attacker run the setuid executable or write to the world-writable location. In the case of the \"system helper\" component, files deployed as part of the app are owned by root, so in the worst case they could be setuid root.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-732"],"references":["http://www.debian.org/security/2017/dsa-3895","http://www.securityfocus.com/bid/99346","https://bugs.debian.org/865413","https://github.com/flatpak/flatpak/issues/845","http://www.debian.org/security/2017/dsa-3895"],"products":["debian:debian_linux","flatpak:flatpak"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-9780","score":0.00355,"percentile":0.29219,"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).
