CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Overton - Creative WordPress Theme for Agencies and Freelancers <= 1.3 takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. No fixed build of this theme is recorded for Overton - Creative WordPress Theme for Agencies and Freelancers yet, so installs running <= 1.3 stay exposed until the vendor ships one.

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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
