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.","state":0,"publishedAt":"2026-10-14T14:37:55.141+00:00","modifiedAt":"2026-10-18T13:34:49.826+00:00","affected":[{"ecosystem":"Vendor product","name":"gitea.com/gitea/runner","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Gitea\",\n                    \"product\": \"Gitea Runner\",\n                    \"packageName\": \"gitea.com/gitea/runner\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"3.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-x4q3-gcj3-m6cf","https://blog.gitea.com/release-of-runner-3.0.0/","https://gitea.com/gitea/runner/releases/tag/v3.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-73802","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-73802","identifiers":["CVE-2026-73802"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
