Overview
The CVE-2026-32272 entry describes an SQL injection vulnerability in Craft Commerce where an input sanitization blocklist failed to cover certain subqueries. This allowed an authenticated control panel user to bypass sanitization and perform boolean-based blind SQL injection to exfiltrate data from the database, potentially revealing security keys that enable forging admin sessions for privilege escalation. While this CVE pertains to Craft Commerce, the underlying flaw-constructing SQL with untrusted input-maps directly to Go (Gin) applications that concatenate strings to build queries without parameters.
Exploitation in the real-world CVE path involved bypassing the top-level sanitization and reintroducing injection through a subquery that was not properly sanitized. In Go Gin, the analogous risk arises when a handler builds a SQL statement by interpolating user input into the query string (for example, via fmt.Sprintf or string concatenation) instead of using parameterized queries. An attacker can craft input that alters the SQL logic (boolean conditions, unions, or data leakage) and, in worst cases, access sensitive data or escalate privileges if secrets or authentication tokens are exposed.
Mitigation in Go (Gin) is to treat all user input as untrusted and never embed it directly in SQL. Use prepared statements, parameterized queries, or ORM abstractions that separate SQL from data. Validate inputs with allowlists, centralize database access to ensure consistent safe patterns, and add tests that simulate crafted inputs. The Go example below demonstrates a vulnerable endpoint alongside a secure alternative, illustrating how to apply the same remediation mindset to Craft Commerce-like injection risks in Go code.
