At a glance
CVE-2024-10673 is a high-severity Missing Authorization vulnerability in the Top Store WordPress theme, affecting versions <= 1.5.4. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.5.5; sites on affected versions should update now. Disclosed November 2024, reported by Sean Murphy.
Vulnerability Overview
The Top Store theme for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the top_store_install_and_activate_callback() function in all versions up to, and including, 1.5.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to install arbitrary plugins which can contain other exploitable vulnerabilities to elevate privileges and gain remote code execution.
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, availability — full site compromise territory.
CWE-862: Missing Authorization
Top Store <= 1.5.4 carries this weakness at top_store_install_and_activate_callback(), and reaching it takes an account at Subscriber level or above. 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 Top Store the fix is 1.5.5: builds <= 1.5.4 are affected, anything from 1.5.5 onward is not.
Remediation
Update to version 1.5.5, 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: Top Store 1.5.5 closes this, and updating the theme is the step that ends it.
