Overview
CVE-2026-6225 reports a time-based blind SQL injection in The Taskbuilder - Project Management & Task Management Tool With Kanban Board plugin for WordPress. The vulnerability occurs via the 'project_search' parameter and stems from insufficient escaping and lack of safe preparation of the SQL query. An authenticated attacker with Subscriber-level access could append additional SQL fragments to an existing query and trigger time-based sleep conditions to reveal data exfiltrated from the database. This CVE is categorized under CWE-89 (SQL Injection). In Go with Gin, similar risks arise when user input is concatenated into raw SQL strings instead of being bound as parameters. If a handler reads a value from the request and builds a query via string concatenation, an attacker could alter the query structure and potentially delay responses (time-based) or leak data, mirroring the real-world impact described by CVE-2026-6225. Remediating this class of vulnerability in Go requires binding user input through parameterized queries or using an ORM that handles binding, along with strict input validation and least-privilege database access. The guidance below demonstrates concrete patterns in Go (Gin) and contrasts a vulnerable pattern with a safe fix.
