At a glance

CVE-2024-50478 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the 1-Click Login WordPress plugin, affecting versions 1.4.5. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2024, reported by stealthcopter.

Vulnerability Overview

The 1-Click Login: Passwordless Authentication plugin for WordPress is vulnerable to authentication bypass in version 1.4.5. This is due to the plugin not properly verifying a user's identity prior to authenticating them. This makes it possible for unauthenticated attackers to log in as other users, such as administrators, granted they have access to an email.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-288: Authentication Bypass Using an Alternate Path or Channel

Reaching this weakness in 1-Click Login 1.4.5 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. No fixed build of this plugin is recorded for 1-Click Login yet, so installs running 1.4.5 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
