BBS e-Franchise 1.1.1 WordPress Plugin SQL Injection via uid

BBS e-Franchise 1.1.1 plugin for WordPress contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the uid parameter. Attackers can craft requests to pages using the plugin's shortcode with UNION-based SQL injection in the uid parameter to extract sensitive data from the WordPress database including user information and taxonomy terms.
