Vulnerability Overview
The Ultimate Addons for Beaver Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.35.14. This makes it possible for authenticated attackers, with contributor access and above, to escalate their privileges to those of a higher level user.
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-269: Improper Privilege Management
Reaching this weakness in Ultimate Addons for Beaver Builder <= 1.35.14 takes an account at Contributor level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Ultimate Addons for Beaver Builder the fix is 1.35.15: builds <= 1.35.14 are affected, anything from 1.35.15 onward is not.
Remediation
Update to version 1.35.15, 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: Ultimate Addons for Beaver Builder 1.35.15 closes this, and updating the plugin is the step that ends it.
