Vulnerability Overview
The HubSpot All-In-One Marketing - Forms, Popups, Live Chat plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.3.32 via the leadin/public/admin/class-adminconstants.php file. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract a list of all installed plugins and their versions which can be leveraged for reconnaissance and further attacks.
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-862: Missing Authorization
Reaching this weakness in HubSpot All-In-One Marketing <= 11.3.32 takes an account at Contributor 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 HubSpot All-In-One Marketing the fix is 11.3.33: builds <= 11.3.32 are affected, anything from 11.3.33 onward is not.
Remediation
Update to version 11.3.33, 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: HubSpot All-In-One Marketing 11.3.33 closes this, and updating the plugin is the step that ends it.
