At a glance
CVE-2025-5394 is a critical-severity Missing Authorization vulnerability in the Alone WordPress theme, affecting versions <= 7.8.3. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 7.8.5; sites on affected versions should update now. Disclosed July 2025, reported by Thái An.
Vulnerability Overview
The Alone – Charity Multipurpose Non-profit WordPress Theme theme for WordPress is vulnerable to arbitrary file uploads due to a missing capability check on the alone_import_pack_install_plugin() function in all versions up to, and including, 7.8.3. This makes it possible for unauthenticated attackers to upload zip files containing webshells disguised as plugins from remote locations to achieve remote code execution. CVE-2025-54019 is likely a duplicate of this.
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-862: Missing Authorization
Alone <= 7.8.3 carries this weakness at alone_import_pack_install_plugin(), and reaching it takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Alone the fix is 7.8.5: builds <= 7.8.3 are affected, anything from 7.8.5 onward is not.
Remediation
Update to version 7.8.5, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Alone 7.8.5 closes this, and updating the theme is the step that ends it.
