ColdFusion App Inaccessible After Kubernetes Deployment Update - Lucid Outsourcing Solutions

Image
  You push a Kubernetes deployment update for your ColdFusion application. The rollout begins, and then everything breaks. Pods restart endlessly, the service returns errors, and users cannot reach the application. Meanwhile, the previous version worked perfectly minutes ago. Read More

ColdFusion Autoscaling Session Inconsistency in the Cloud - Lucid Outsourcing Solutions

Image
  Your ColdFusion application runs in the cloud behind an autoscaling group. Traffic surges, so new instances spin up automatically. Then traffic drops, and the platform terminates instances. Suddenly, users report being logged out at random. Read More

ColdFusion XSS Vulnerability in Form Input: Causes, Fixes & Best Practices

Image
  Your ColdFusion form accepts user input. It saves a name, a comment, or a search term. Later, your application displays that input on a page. If you display it without encoding, you may have just executed an attacker’s script. Read More

ColdFusion LDAP Authentication Failing Intermittently: Causes & Fixes - Lucid Outsourcing Solutions

Image
  Your ColdFusion application authenticates users against Active Directory. Most of the time, it works perfectly. Then, without warning, logins start failing. Minutes later, they work again, as if nothing happened. Read More

ColdFusion Secure Cookie Not Working Over HTTPS - Lucid Outsourcing Solutions

Image
  You configure a secure cookie in ColdFusion. Your site runs entirely over HTTPS. Yet the browser never receives the Secure flag. Worse, the cookie sometimes disappears entirely after a login redirect. Read More

ColdFusion Modal Popup Not Submitting Form Data: Causes, Fixes & Best Practices - Lucid Outsourcing Solutions

Image
  ColdFusion modal popups power contact forms, login dialogs, data entry panels, and confirmation screens. Therefore, reliable form submission from inside a modal is a core enterprise requirement. Yet developers consistently hit a wall. The button clicks, nothing posts, and the user stares at a frozen popup. Read More

ColdFusion PDF Not Displaying in Browser: Causes, Fixes & Best Practices - Lucid Outsourcing Solutions

Image
  ColdFusion generates PDFs for invoices, reports, statements, and contracts. Therefore, reliable PDF delivery sits at the core of many enterprise apps. Yet developers often watch a cfdocument output fail in the browser. The page shows a blank frame, a download prompt, or corrupted bytes. Read More

ColdFusion External API SSL Certificate Validation Error | Lucid Outsourcing Solutions

Image
  Introduction The integration works perfectly in staging. The mobile app calls the payment API through ColdFusion. Tokens authenticate. Transactions process. Then deployment to production fails with a cryptic message: “I/O Exception: sun.security.validator.ValidatorException: PKIX path building failed: java.security.cert.CertPathBuilderException: Could not build a validated path.” The API is up. Browsers connect to it without errors. Curl from the production server works fine. But ColdFusion refuses to talk to it. The error message points at Java security internals that most CFML developers have never read. Read More

ColdFusion API Authentication Token Not Refreshing Automatically - Lucid Outsourcing Solutions

Image
The integration runs flawlessly during the demo. Tokens authenticate cleanly. API calls succeed. Then an hour later, every call starts returning 401 Unauthorized. The integration sees the failure, refreshes the token, retries the call, and succeeds. The user experience is fine — but every hour, a brief window of failures occurs while the code reacts to expiration. Then twenty-four hours later, the failures stop being temporary. The refresh attempts also return 401. The refresh token expired. Users are silently logged out. The integration breaks completely until someone manually triggers re-authentication. Read More

ColdFusion REST API Returning 500 Internal Server Error - Lucid Outsourcing Solutions

Image
  Introduction The mobile app posts JSON to the ColdFusion REST endpoint. The endpoint returns “500 Internal Server Error” with no body, no useful header information, and no error message that helps diagnose the problem. The frontend developer asks the backend developer for help. The backend developer checks the ColdFusion error log — nothing recent. The exception log — empty. The Application.cfc onError handler — never fired. The endpoint works in Postman with the right request body. It fails with a 500 when the mobile app sends what looks like an identical request. The cause is invisible from every diagnostic angle except one — and that one is buried in a stack trace nobody thought to check. Read More

ColdFusion Unicode Characters Not Saving Correctly in Database - Lucid Outsourcing Solutions

Image
  Introduction The user types José in the form. The browser sends “José” correctly. ColdFusion processes the request. The database stores “Jos?”. The user types Москва. The database stores “??????”. The user types 中文. The database stores “??”. Or worse — the data appears correct in SQL Server Management Studio but corrupts the moment ColdFusion reads it back. Every test in isolation works. The full pipeline silently destroys non-ASCII characters somewhere between keyboard and disk. Read More

ColdFusion Transaction Rollback Not Working Properly - Lucid Outsourcing Solutions

Image
  Introduction The code reads two database tables. It updates an inventory record. It inserts an order line. It updates the customer’s loyalty balance. Halfway through, the loyalty update fails — the column does not exist on the customer table after a schema change nobody documented. ColdFusion throws an error. You expect the transaction to roll back. You expect the inventory and order records to revert. You expect the database to look exactly as it did before the operation started. You expect atomicity. What you get is an inventory record that decremented, an order line that exists with a phantom customer reference, and an error log entry that says nothing about why the rollback failed. Read More

Why Patching ColdFusion Without a JDK Update Still Leaves Your Server Exposed | Lucid Outsourcing Solutions

Image
  Applying the latest Adobe ColdFusion security update (APSB) does not update the underlying Oracle JDK that ColdFusion runs on. Adobe ships ColdFusion 2021 with Java 11, 2023 with Java 17, and 2025 with Java 21 — but the bundled JRE folder is frozen at whatever Java version shipped with the installer. Oracle releases JDK security patches quarterly, and recent Critical Patch Updates have closed unauthenticated, network-exploitable flaws in Java SE itself. If your CF team patches CF but never touches the JDK, your server keeps every Java-level CVE Oracle has fixed since your install — even after every APSB is current. The fix is a separate, manual JDK update process documented by Adobe. Read More

ColdFusion ORM Not Saving Data Correctly: Guide | Lucid Outsourcing Solutions

Image
  Introduction The code looks correct. You create an entity. You set properties. You call EntitySave() . The page returns. No errors. No warnings. Nothing in the log. But the database is empty. Or the parent record saved while the child records did not. Or every field has the correct value except one — which mysteriously stayed null. Or the same code that worked yesterday in development saves nothing in production. Read More
