CVE-2024-52586Network attack vector

Authenticated MFA bypass

Published Dec 9, 2024 · Updated Dec 10, 2024

Authentication bypass in Deltablot eLabFTW 4.6.0 through 5.1.8 allows remote authenticated users to log in without built-in MFA. The advisory does not identify the alternate authentication path or code-level operation that skips the built-in second-factor check. A valid local account password is required; SSO-provider MFA is unaffected, while built-in MFA no longer prevents account access.
