Prior to version 2.4.0, `POST /api/auth/token` authenticates with username and password only, then calls `getTokens()`, which returns full access and refresh JWTs without checking whether the account has TOTP 2FA enabled. An attacker with stolen or phished credentials can bypass 2FA in a single request. The parallel login endpoint (`POST /api/auth/login`) correctly enforces 2FA by calling `setCookies(user, res, true)`, which gates on `user.twoFaEnabled`. Version 2.4.0 patches the issue.","evidence":"cve:CVE-2026-58269","products":[{"name":{"value":"server","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-58269","aliases":["CVE-2026-58269"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":8.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"Sync-in","product":"server","versions":[{"status":"affected","version":"< 2.4.0"}]}],"modified":"2026-09-24T22:38:27.013Z","provider":"cve","references":["https://github.com/Sync-in/server/security/advisories/GHSA-92cr-jxw4-5wjg"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-58269","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-09-24T22:38:05.475667Z"}}}],"references":[{"url":"https://github.com/Sync-in/server/security/advisories/GHSA-92cr-jxw4-5wjg","tags":["exploit"]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T22:38:27.013Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-21T20:01:56.322Z"}}},"related_cves":[{"value":"CVE-2026-58269","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":["publisher_severity"],"severity":"high","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"high"},"context_update":false}],"next_after":1957,"next_before":1957}
