CVE-2025-8570
At a glance
CVE-2025-8570 is a critical-severity Use of Hard-coded Credentials vulnerability in the BeyondCart Connector WordPress plugin, affecting versions <= 3.0.1. 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 3.0.2; sites on affected versions should update now. Disclosed September 2025, reported by kr0d.
Vulnerability Overview
The BeyondCart Connector plugin for WordPress is vulnerable to Privilege Escalation due to improper JWT secret management and authorization within the determine_current_user filter in versions 1.4.2 through 3.0.1. This makes it possible for unauthenticated attackers to craft valid tokens and assume any user’s identity.
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-798: Use of Hard-coded Credentials
The product contains hard-coded credentials, such as a password or cryptographic key.
Remediation
Update to version 3.0.2, 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: BeyondCart Connector 3.0.2 closes this, and updating the plugin is the step that ends it.
