At a glance
CVE-2025-6187 is a critical-severity Missing Authorization vulnerability in the bSecure WordPress plugin, affecting versions 1.3.7 – 1.7.9. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed July 2025, reported by kr0d.
Vulnerability Overview
The bSecure plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization within its order_info REST endpoint in versions 1.3.7 through 1.7.9. The plugin registers the /webhook/v2/order_info/ route with a permission_callback that always returns true, effectively bypassing all authentication. This makes it possible for unauthenticated attackers who know any user’s email to obtain a valid login cookie and fully impersonate that account.
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-862: Missing Authorization
Reaching this weakness in bSecure 1.3.7 – 1.7.9 takes no account at all. 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. No fixed build of this plugin is recorded for bSecure yet, so installs running 1.3.7 – 1.7.9 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
