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.
CWE-862: Missing Authorization
Reaching this weakness in Masterstudy - Education WordPress Theme < 4.8.122 takes a caller who can reach the endpoint. 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 Masterstudy - Education WordPress Theme the fix is 4.8.122: builds < 4.8.122 are affected, anything from 4.8.122 onward is not.
Remediation
Update to version 4.8.122, 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: Masterstudy - Education WordPress Theme 4.8.122 closes this, and updating the theme is the step that ends it.
