Host namespace settings, expanded capabilities, and security profile overrides can remain effective despite Privileged being forced false. A workflow author able to run jobs on an affected Docker-backed runner can use these options to access host namespaces and execute commands as root on the runner host, bypassing the intended container isolation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://blog.gitea.com/release-of-runner-3.0.0/","https://gitea.com/gitea/runner/releases/tag/v3.0.0","https://github.com/go-gitea/gitea/security/advisories/GHSA-x4q3-gcj3-m6cf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-73802","score":0.00472,"percentile":0.40569,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-x4q3-gcj3-m6cf","url":"https://osv.dev/vulnerability/GHSA-x4q3-gcj3-m6cf","summary":"gitea-runner: workflow container.options passes host namespaces and capability flags to job container when privileged mode is disabled","modified":"2026-10-07T17:55:44.795358931Z","packages":[{"ecosystem":"Go","name":"gitea.com/gitea/runner","purl":"pkg:golang/gitea.com/gitea/runner","ranges":["<1.0.9-0.20260731160927-34bfa1915022"],"fixed":["1.0.9-0.20260731160927-34bfa1915022"]}]},{"id":"GO-2026-6656","url":"https://osv.dev/vulnerability/GO-2026-6656","summary":"gitea-runner: workflow container.options passes host namespaces and capability flags to job container when privileged mode is disabled in gitea.com/gitea/runner","modified":"2026-10-07T17:45:12.474497003Z","packages":[{"ecosystem":"Go","name":"gitea.com/gitea/runner","purl":"pkg:golang/gitea.com/gitea/runner","ranges":["<1.0.9-0.20260731160927-34bfa1915022"],"fixed":["1.0.9-0.20260731160927-34bfa1915022"]}]}],"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).
