Thread: How can you prevent SOQL injection in Salesforce Apex?

To prevent SOQL injection in Salesforce Apex, it is crucial to use bind variables in your SOQL queries. Bind variables ensure that user input is treated as data and not executable code, which effectively mitigates the risk of injection attacks. SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language) are essential tools in Salesforce for querying and searching records. Misusing these languages can expose your Apex code to security vulnerabilities. You can learn more about SOQL and SOSL on our website by visiting the SOQL and SOSL pages. Here is an example of how to use bind variables to prevent SOQL injection:

Code:

public List<Account> getAccounts(String userInput) {
    // Using bind variable to prevent SOQL injection
    String query = 'SELECT Id, Name FROM Account WHERE Name = :userInput';
    List<Account> accounts = Database.query(query);
    return accounts;
}

In this example, userInput is safely incorporated into the SOQL query using the bind variable :userInput. This method ensures that the input is treated as a parameter and not as a part of the query string, thus preventing SOQL injection attacks.
