Description

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.
