Vulnerability Overview
The Frontend Post Submission Manager Lite – Frontend Posting WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_global_settings and process_form_edit functions in all versions up to, and including, 1.2.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's settings and forms.
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 interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in Frontend Post Submission Manager Lite <= 1.2.2 takes an account at Subscriber level or above. 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 Frontend Post Submission Manager Lite the fix is 1.2.3: builds <= 1.2.2 are affected, anything from 1.2.3 onward is not.
Remediation
Update to version 1.2.3, or a newer patched version
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. None of that substitutes for the fix: Frontend Post Submission Manager Lite 1.2.3 closes this, and updating the plugin is the step that ends it.
