At a glance
CVE-2025-0177 is a critical-severity Improper Privilege Management vulnerability in the Javo Core WordPress plugin, affecting versions <= 3.0.0.080. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.0.0.266; sites on affected versions should update now. Disclosed March 2025, reported by Tonn.
Vulnerability Overview
The Javo Core plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 3.0.0.080. This is due to the plugin allowing users who are registering new accounts to set their own role. This makes it possible for unauthenticated attackers to gain elevated privileges by creating an account with the administrator role.
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 privileges on the target site, 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 Javo Core <= 3.0.0.080 takes no account at all. 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 Javo Core the fix is 3.0.0.266: builds <= 3.0.0.080 are affected, anything from 3.0.0.266 onward is not.
Remediation
Update to version 3.0.0.266, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Javo Core 3.0.0.266 closes this, and updating the plugin is the step that ends it.
