A party able to authenticate through the affected external identity flow can obtain a full session without the passkey verification enforced during password login. One affected path can also persist an external identity link, extending the compromise beyond the initial session; accounts with TOTP configured are outside the reported WebAuthn-only scenario.","state":0,"publishedAt":"2026-10-06T19:33:54.375+00:00","modifiedAt":"2026-10-07T20:00:46.107+00:00","affected":[{"ecosystem":"Vendor product","name":"gitea.dev","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Gitea\",\n                    \"product\": \"Gitea\",\n                    \"packageName\": \"gitea.dev\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"1.16.0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.27.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-92j2-6qcg-c28c","https://blog.gitea.com/release-of-1.27.2/","https://github.com/go-gitea/gitea/pull/38805","https://github.com/go-gitea/gitea/pull/38810","https://github.com/go-gitea/gitea/releases/tag/v1.27.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-73278","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-73278","identifiers":["CVE-2026-73278"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
