+  "details": "### Impact\n\nSQL Injection can occur when:\n\n1. The non-default simple protocol is used.\n2. A dollar quoted string literal is used in the SQL query.\n3. That string literal contains text that would be would be interpreted as a placeholder outside of a string literal.\n4. The value of that placeholder is controllable by the attacker.\n\ne.g.\n\n```go\nattackValue := `$tag$; drop table canary; --`\n_, err = tx.Exec(ctx, `select $tag$ $1 $tag$, $1`, pgx.QueryExecModeSimpleProtocol, attackValue)\n```\n\nThis is unlikely to occur outside of a contrived scenario.\n\n### Patches\n\nThe problem is resolved in v5.9.2.\n\n### Workarounds\n\nDo not use the simple protocol to execute queries matching all the above conditions.",
