Cybersecurity discussions often spotlight phishing scams, ransomware attacks and other external threats. But there’s a foundational risk that quietly underpins many of these issues: poor handling of file uploads and delivery. In 2024, malicious file detections rose 14% over the previous year, but the issue isn’t just the presence of harmful files– it’s the everyday systems that allow them in.
Businesses that allow end-users to upload content often rely on quick solutions in the early days. Early on, a handful of open-source tools or DIY systems might suffice. But when user numbers climb, so does the risk. Without proper safeguards, uploaded files can become the entry point for malware, phishing, inappropriate content or even data leaks.
The Hidden Dangers of Poor File Management
Underestimating Complexity at Scale
For small teams, building a basic upload and delivery workflow in-house might seem like a practical solution. However, as operations scale and file types multiply– from user-uploaded images and videos to sensitive documents– the demand quickly grows. CTOs who initially build their own systems often discover that managing file security, performance and compliance becomes significantly more challenging over time. Without dedicated infrastructure, ensuring compliance and preventing vulnerabilities becomes a constant drain on resources– one that purpose-built solutions handle out of the box.
Unfiltered Uploads that Disrupt Operations
When businesses fail to properly secure file uploads and public file access, they expose themselves to vulnerabilities. Unlike database breaches, the risks here are tied to how external users upload files–whether it’s large files, unsupported formats or malicious code embedded within images or documents. If these files aren’t properly vetted, they can disrupt a business’s operations, potentially bringing down websites or systems While end users might not directly see the breach, the result is often a site that’s down, buggy or vulnerable to follow up intrusions, potentially costing revenue.
For instance, let’s take a look at the XSS attack discovered in Shopify’s avatar upload system. A researcher found that by exploiting unrestricted file uploads, attackers could inject malicious code into PNG image files using metadata and bypassing security checks. Once the file was delivered through Shopify’s CDN, the attacker executed JavaScript in users’ browsers, potentially stealing sensitive data and enabling phishing attacks.
Security Breaches from Publicly Accessible Files
Another risk comes from unprotected public URLs. Files delivered through public URLs can be easily accessed by unauthorized users if no security measures are in place. These files could be exploited for further attacks or be used inappropriately if access control is lacking. The complexity of securing these external file uploads and deliveries underscores the importance of using purpose-built solutions that automatically enforce these security protocols.
How to Secure Your File Management System
Built-In Security Infrastructures
Securing file uploads and delivery requires more than just monitoring internal systems. Businesses that allow external users to upload files– such as images, videos or documents– need guardrails to prevent abuse. These include scanning for malware, moderating for inappropriate or copyrighted content, verifying file size and format and protecting access with signed URLs. While these measures are essential, building and maintaining them in-house can be time consuming and costly. Purpose-built platforms often provide these protections by default, helping teams stay focused on their core product while reducing security risk.
Use Secure APIs Instead of DIY Solutions
Building a custom file management system might offer initial flexibility, but the ongoing maintenance and security challenges can quickly outweigh the benefits. Instead, many organizations find that secure APIs provide a more robust solution. These APIs are designed with encryption, access controls, and compliance in mind, reducing the risk associated with a homegrown solution.
For instance, platforms like Uploadcare offer a comprehensive suite of tools that handle file uploads, management, and delivery securely, so you can focus on your core business without compromising on file security.
Last Thoughts
Insufficient management for file uploads and delivery is more than an operational inconvenience—it’s a significant cybersecurity risk that grows in proportion to your organization’s scale. Whether it’s an outdated system, a data exposure incident, or XSS attacks, the consequences of neglecting robust file management can be severe.
By regularly updating dependencies and opting for secure, managed file handling solutions, companies can mitigate these risks and protect both their data and their reputation. In today’s digital landscape, proactive file management isn’t just a technical necessity—it’s a foundational pillar of an effective cybersecurity strategy.
