At a glance
CVE-2023-47783 is a high-severity Missing Authorization vulnerability in the Thrive Themes Builder WordPress theme, affecting versions < 3.24.0. It carries a CVSS score of 8.3 (reachable over the network; low attack complexity; high confidentiality, integrity impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 3.24.0; sites on affected versions should update now. Disclosed November 2023, reported by Rafie Muhammad.
Vulnerability Overview
The Thrive Theme Builder theme for WordPress is vulnerable to unauthorized use of functionality due to missing capability check in one of its functions in versions prior to 3.24.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to invoke this function intended for higher-privileged users. The exact impact of this vulnerability is not known.
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. A successful exploit has high impact on confidentiality, integrity.
CWE-862: Missing Authorization
Reaching this weakness in Thrive Themes Builder < 3.24.0 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 Thrive Themes Builder the fix is 3.24.0: builds < 3.24.0 are affected, anything from 3.24.0 onward is not.
Remediation
Update to version 3.24.0, 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: Thrive Themes Builder 3.24.0 closes this, and updating the theme is the step that ends it.
