Vulnerability Overview
The PSW Front-end Login & Registration plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.12 via the customer_registration() function. This is due to the use of a weak, low-entropy OTP mechanism in the forget() function. This makes it possible for unauthenticated attackers to initiate a password reset for any user, including administrators, and elevate their privileges for full site takeover.
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-330: Use of Insufficiently Random Values
The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.
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?
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
