Live › vulnerability › CVE-2024-27928
A vantage6 user whose email account is compromised can reset their password through email, then reset the 2FA token through email, reducing login protection to email access alone. The maintainer notes most email providers require 2FA themselves, so this is unlikely to be exploited often.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-11-03 16:15 UTC, 0h before NVD. All times on this page are UTC.
Teams running the vantage6 Python package, in deployments where users have 2FA and password reset goes through email. The advisory states no patches or workarounds are available in the advisory itself. unknown whether the fixed version changes the reset flow, as the sources do not say.
| Product | Ecosystem | Affected | Fixed in |
|---|---|---|---|
| vantage6 | pypi | < 5.0.0 | 5.0.0 |
vantage6 package is below 5.0.0 (for example with pip show vantage6).vantage6 upgrade to 5.0.0 or later.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
If an attacker hacks into a vantage6 user's email account, they can 1) reset the password via email and then 2) reset the 2FA token via email. This way they reduce 2FA to 1FA (email access).
Note that most email providers require 2FA to access email, so this issue is not very likely to cause issues.
Many web apps do not provide functionality to reset 2FA token (probably for this reason), but provide recovery codes as well. It would be better to provide these recovery codes to the user 1 time and then delete the option to reset it.
An alternative may be to only let server administrators reset 2FA token. However, this has as disadvantage that a hacked email account may send messages to the server admin to reset them, which they may fall for.
