SCA: security update for github.com/authelia/authelia/v4 (GHSA-m5mf-3963-4x26)
low Tenable Self-Hosted Container Security Plugin ID 420919
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Authelia is an open-source authentication and authorization server providing two-factor authentication and
single sign-on (SSO) for applications via a web portal. If users are allowed to sign in via both username
and email the regulation system treats these as separate login events. This leads to the regulation
limitations being effectively doubled assuming an attacker using brute-force to find a user password. It's
important to note that due to the effective operation of regulation where no user-facing sign of their
regulation ban being visible either via timing or via API responses, it's effectively impossible to
determine if a failure occurs due to a bad username password combination, or a effective ban blocking the
attempt which heavily mitigates any form of brute-force. This occurs because the records and counting
process for this system uses the method utilized for sign in rather than the effective username attribute.
This has a minimal impact on account security, this impact is increased naturally in scenarios when there
is no two-factor authentication required and weak passwords are used. This makes it a bit easier to brute-
force a password. A patch for this issue has been applied to versions 4.38.19, and 4.39.0. Users are
advised to upgrade. Users unable to upgrade should 1. Not heavily modify the default settings in a way
that ends up with shorter or less frequent regulation bans. The default settings effectively mitigate any
potential for this issue to be exploited. and 2. Disable the ability for users to login via an email
address. (CVE-2025-24806)
