Overview
SQL injection is a critical risk, exemplified by CVE-2026-6674 in a WordPress plugin where insufficient escaping of a user-supplied parameter allowed an authenticated attacker to append SQL to existing queries (CWE-89). This could enable data exfiltration or modification, depending on the query and database privileges. This vulnerability class-SQL injection via untrusted input-illustrates how attackers can manipulate application queries to access sensitive data. The CVE highlights the broader risk when user input is not properly sanitized or bound to a prepared statement, enabling attackers to subvert the intended data access controls.
