At a glance
CVE-2026-27390 is a high-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the WeDesignTech Ultimate Booking Addon WordPress plugin, affecting versions <= 1.0.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact).

Disclosed February 2026, reported by Phat RiO.
Vulnerability Overview
The WeDesignTech Ultimate Booking Addon plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.0.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to bypass authentication and log in to other users accounts, which may include administrators.
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-288: Authentication Bypass Using an Alternate Path or Channel
Reaching this weakness in WeDesignTech Ultimate Booking Addon <= 1.0.1 takes an account at Subscriber level or above. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.
The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. No fixed build of this plugin is recorded for WeDesignTech Ultimate Booking Addon yet, so installs running <= 1.0.1 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?
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
