{"id":"CVE-2026-28510","summary":"elabftw allows MFA bypass during login","details":"eLabFTW is an open source electronic lab notebook. In elabftw versions through 5.4.1, the login flow did not reliably preserve the multi-factor authentication state across authentication steps. Under certain conditions, an attacker with valid primary credentials could complete authentication with an attacker-controlled TOTP secret and bypass the additional factor. This could result in unauthorized account access. This issue is fixed in version 5.4.2.","aliases":["GHSA-x5wv-c9q4-fj65"],"modified":"2026-07-15T01:49:08.519548841Z","published":"2026-05-05T12:28:10.380Z","database_specific":{"cwe_ids":["CWE-302"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28510.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28510.json"},{"type":"ADVISORY","url":"https://github.com/elabftw/elabftw/security/advisories/GHSA-x5wv-c9q4-fj65"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28510"},{"type":"FIX","url":"https://github.com/elabftw/elabftw/commit/8b7a575aef128870861187eaa2b2f0f08654ecf9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/elabftw/elabftw","events":[{"introduced":"0"},{"fixed":"edf271bce2e7675b59158e1a603845e3fe4ba3d3"},{"fixed":"8b7a575aef128870861187eaa2b2f0f08654ecf9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.4.2"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:elabftw:elabftw:*:*:*:*:*:*:*:*"}}],"versions":["= 5.4.1","5.4.1","5.4.0","5.4.0-beta2","5.4.0-beta","5.4.0-alpha3","5.4.0-alpha2","5.4.0-alpha","5.3.2","5.3.1","5.3.0","5.3.0-rc","5.3.0-beta3","5.3.0-beta2","5.3.0-beta","5.3.0-alpha6","5.3.0-alpha5","5.3.0-alpha4","5.3.0-alpha3","5.3.0-alpha2","5.3.0-alpha","5.2.3","5.2.2","5.2.1","5.2.0","5.2.0-beta2","5.2.0-beta","5.2.0-alpha5","5.2.0-alpha4","5.2.0-alpha3","5.2.0-alpha","5.2.0-alpha2","5.1.7","5.1.6","5.1.5","5.1.4","5.1.3","5.1.2","5.1.1","5.1.0","5.1.0-beta4","5.1.0-beta3","5.1.0-beta2","5.1.0-beta","5.1.0-alpha4","5.1.0-alpha3","5.1.0-alpha2","5.1.0-alpha","5.0.0","5.0.0-beta3","5.0.0-beta2","5.0.0-beta","5.0.0-alpha4","5.0.0-alpha3","5.0.0-alpha2","5.0.0-alpha","4.9.0","4.9.0-beta2","4.9.0-beta","4.9.0-alpha","4.8.3","4.8.2","4.8.1","4.8.0","4.8.0-beta","4.8.0-alpha","4.7.0","4.6.1","4.6.0","4.6.0-beta2","4.6.0-beta","4.6.0-alpha4","4.6.0-alpha3","4.6.0-alpha2","4.6.0-alpha","4.5.12","4.5.4","4.5.3","4.5.2","4.5.1","4.5.0","4.5.0-beta3","4.5.0-beta2","4.5.0-beta","4.4.3","4.4.2","4.4.1","4.4.0","4.4.0-beta7","4.4.0-beta6","4.4.0-beta5","4.4.0-beta4","4.4.0-beta3","4.4.0-beta2","4.4.0-beta","4.4.0-alpha5","4.4.0-alpha4","4.4.0-alpha3","4.4.0-alpha2","4.4.0-alpha","4.3.3","4.3.2","4.3.1","4.3.0","4.3.0-beta5","4.3.0-beta4","4.3.0-beta3","4.3.0-beta2","4.3.0-beta","4.3.0-alpha","4.2.2","4.2.1","4.2.0","4.2.0-BETA","4.1.0","4.1.0-BETA6","4.1.0-BETA5","4.1.0-BETA4","4.1.0-BETA3","4.1.0-BETA2","4.1.0-BETA","4.0.11","4.0.10","4.0.9","4.0.8","4.0.7","4.0.6","4.0.5","4.0.4","4.0.3","4.0.2","4.0.1","4.0.0","4.0.0-beta6","4.0.0-beta5","4.0.0-beta4","4.0.0-beta3","4.0.0-beta2","4.0.0-beta","4.0.0-alpha2","4.0.0-alpha","3.6.4","3.6.3","3.6.2","3.6.1","3.6.0","3.6.0-rc","3.6.0-beta","3.6.0-alpha","3.5.4","3.5.3","3.5.2","3.5.1","3.5.0","3.5.0-rc","3.5.0-beta","3.4.10","3.4.9","3.4.8","3.4.7","3.4.6","3.4.5","3.4.4","3.4.3","3.4.2","3.4.1","3.4.0","3.4.0-beta","3.4.0-alpha","3.3.12","3.3.11","3.3.10","3.3.9","3.3.8","3.3.7","3.3.6","3.3.5","3.3.4","3.3.3","3.3.2","3.3.1","3.3.0","3.2.2","3.2.1","3.2.0","3.1.2","3.1.1","3.1.0","3.0.3","3.0.2","3.0.1","3.0.0","3.0.0-beta","3.0.0-alpha","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","2.0.0-beta","2.0.0-alpha2","2.0.0-alpha1","1.8.3","1.8.2","1.8.1","1.7.8","1.7.7","1.7.6","1.7.4","1.7.3","1.7.2","1.7.1","1.7.0","1.6.2","1.6.1","1.6.0","1.5.7","1.5.6","1.5.5","1.5.4","1.5.3","1.5.2","1.5.1","1.5.0","1.3.0","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0-p3","1.2.0-p2","1.2.0-p1","1.2.0","1.2.0-beta","1.2.0-alpha","1.1.8-p2","1.1.8-p1","1.1.8","1.1.7","1.1.6","1.1.5-p1","1.1.5","1.1.5-beta","1.1.4-p2","1.1.4-p1","1.1.4","1.1.3","1.1.2-p1","1.1.2","1.1.0","1.0.0","1.0.0-beta","1.0.0-alpha","0.12.5","0.12.4","0.12.3","0.12.2","0.12.1","0.12.0","0.12.0-BETA","0.11.0a","0.11.0","0.11.0-RC","0.10.1","0.10.0","0.9.4.2","0.9.4","0.8.3","0.8.2","0.8.1","0.8","0.7.3.2","0.7.3.1","0.7.3","0.7.2","0.7.1","0.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28510.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N"}]}
