Analysis

AI-generated

Technical impact

Authentication Bypass Using an Alternate Path or Channel in the WeDesignTech Ultimate Booking Addon allows an attacker to abuse authentication controls and gain unauthorized access to user accounts. The vulnerability is a CWE-288 weakness that can enable attackers to assume legitimate user credentials, potentially leading to destructive actions, data exfiltration, or further compromise of the WordPress site.

Affected Systems

The flaw affects the WordPress plugin WeDesignTech Ultimate Booking Addon in any version up to and including 1.0.1. WordPress sites running these versions are at risk.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity, while the EPSS score of less than 1% suggests exploitation is currently unlikely but still possible. The exploit likely involves manipulating HTTP requests to bypass authentication checks, potentially via crafted URLs or API endpoints. Attackers would need the ability to send requests to the vulnerable plugin but do not require privileged access, making the vulnerability a moderate to high risk for exposed sites.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the WeDesignTech Ultimate Booking Addon plugin to the latest version that addresses the authentication bypass.
  • If an update is not immediately available, temporarily deactivate or uninstall the plugin to eliminate the attack surface.
  • Enforce strong password policies and enable two‑factor authentication for all WordPress administrative accounts.
  • Implement input validation and request filtering to detect and block malformed authentication requests.
