Executive brief
The TechLink theme for WordPress is vulnerable to a security flaw that allows unauthorized users to inject malicious code. This could lead to a complete takeover of the website, theft of customer data, or a total service outage. Business owners using this theme should update to version 1.4 immediately to prevent potential mass-exploitation campaigns.
