At a glance
CVE-2024-53822 is a critical-severity Missing Authorization vulnerability in the Pie Register Premium WordPress plugin, affecting versions < 3.8.3.3. 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 3.8.3.3; sites on affected versions should update now. Disclosed December 2024, reported by Ananda Dhakal.
Vulnerability Overview
The Pie Register Premium plugin for WordPress is vulnerable to arbitrary file uploads in all versions up to 3.8.3.3 (exclusive). This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
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
Reaching this weakness in Pie Register Premium < 3.8.3.3 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 Pie Register Premium the fix is 3.8.3.3: builds < 3.8.3.3 are affected, anything from 3.8.3.3 onward is not.
Remediation
Update to version 3.8.3.3, 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: Pie Register Premium 3.8.3.3 closes this, and updating the plugin is the step that ends it.
