Vulnerability Overview
The Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Open Redirection in all versions up to, and including, 1.2.7 due to insufficient validation on the 'requested_page' POST parameter in the verify_username_password function. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action such as clicking on a link.
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.
CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
Frontend Post Submission Manager Lite 1.0.0 – 1.2.7 carries this weakness at requested_page, and reaching it takes no account at all. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.
A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For Frontend Post Submission Manager Lite the fix is 1.2.8: builds 1.0.0 – 1.2.7 are affected, anything from 1.2.8 onward is not.
Remediation
Update to version 1.2.8, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Frontend Post Submission Manager Lite 1.2.8 closes this, and updating the plugin is the step that ends it.
