At a glance
CVE-2024-1564 is a medium-severity Incorrect Authorization vulnerability in the Schema Pro WordPress plugin, affecting versions <= 2.7.15. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 2.7.16; sites on affected versions should update now. Disclosed March 2024, reported by Scott Kingsley Clark.
Vulnerability Overview
The Schema Pro plugin for WordPress is vulnerable to unauthorized access of data due to a missing or incorrect capability check in all versions up to, and including 2.7.15. This makes it possible for authenticated attackers, with contributor-level access and above, to access arbitrary custom fields.
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-863: Incorrect Authorization
Reaching this weakness in Schema Pro <= 2.7.15 takes an account at Contributor level or above. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.
The action runs for users the code intended to exclude, with the same effect as having no check at all. For Schema Pro the fix is 2.7.16: builds <= 2.7.15 are affected, anything from 2.7.16 onward is not.
Remediation
Update to version 2.7.16, 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: Schema Pro 2.7.16 closes this, and updating the plugin is the step that ends it.
