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 Embed Plus for YouTube Gallery, Livestream and Lazy Loading with Facades <= 14.2.4 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 Embed Plus for YouTube Gallery, Livestream and Lazy Loading with Facades the fix is 14.2.5: builds <= 14.2.4 are affected, anything from 14.2.5 onward is not.
Remediation
Update to version 14.2.5, 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: Embed Plus for YouTube Gallery, Livestream and Lazy Loading with Facades 14.2.5 closes this, and updating the plugin is the step that ends it.
