<p>Scalable vector graphics files, or SVGs, are a staple in modern design. They’re lightweight, resolution-independent, and perfect for responsive human interfaces. </p>



<p>From icons to illustrations, SVGs help teams create polished assets on tight timelines. The catch is, SVGs are more than just images; they’re code. This format means they can carry hidden functionality, like scripts and links.&nbsp;</p>



<p>If left unchecked, these files can become countless points of vulnerability, individual delivery systems for malware. Designers, product teams, and front-end engineers always work with SVGs, so knowing the risks is important. </p>



<p>This insight from <a href="https://octet.design/journal/" target="_blank" rel="noreferrer noopener">Design Journal</a> will explore how security awareness at this stage can stop unsafe assets from being deployed in production environments.&nbsp;</p>



<h2 class="wp-block-heading">How malware hides in SVGs?</h2>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="700" height="400" src="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/1-16.webp" alt="How malware hides in SVGs?" class="wp-image-30897" srcset="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/1-16.webp 700w, https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/1-16-300x171.webp 300w" sizes="auto, (max-width: 700px) 100vw, 700px" /></figure>



<p>Unlike conventional <a href="https://www.adobe.com/acrobat/hub/guide-to-image-file-formats.html" target="_blank" rel="noreferrer noopener nofollow">image types</a>, like JPEGs and PNGs, SVG is written in XML code. Attackers exploit this by inserting malicious instructions into the code that executes when the file is loaded. </p>



<p>Common tricks include sticking <a href="https://pieces.app/collections/javascript" target="_blank" rel="noreferrer noopener">JavaScript snippets</a> inside &lt;script&gt; tags. These can also be hidden with event handlers like onclick and onload. When activated, these commands can cause redirects, malware installations, data harvesting, and more.</p>



<p>External references are another significant risk. An SVG could call out to a third-party URL and pull in malicious code that users are never privy to. In some cases, an attacker can use &lt;foreignObject&gt; tags. </p>



<p>These tags let HTML and certain other code flavors live on or in the SVG. This capability creates the possibility for <a href="https://www.geeksforgeeks.org/blogs/introduction-to-scripting-languages/" target="_blank" rel="noreferrer noopener nofollow">scripting</a> across sites and using other exploits.&nbsp;</p>



<h2 class="wp-block-heading">Real risks in real workflows</h2>



<p>Security issues with SVGs aren’t just theoretical; they appear in everyday design work. <a href="https://octet.design/journal/outline-icons/" target="_blank" rel="noreferrer noopener">Outline Icons</a> and  packs are one of the most common examples. </p>



<p>Designers download free or low-cost bundles from online marketplaces, which is normally just fine. However, when the source isn’t vetted, the files could contain more than you bargained for.&nbsp;</p>



<p>User-generated uploads are another weak point. When platforms let users upload SVGs for avatars, ads, or custom designs, attackers can slip in malicious files that run when others view them.</p>



<p>Third-party libraries and <a href="https://github.com/orgs/github/repositories" target="_blank" rel="noreferrer noopener nofollow">GitHub repositories</a> also pose risks. Teams eager to move fast may pull assets directly into projects without scanning them. Even one compromised SVG can spread malware through a website or app. Recognize potential vulnerabilities and close gaps before deploying assets.</p>



<h2 class="wp-block-heading">Potential consequences of insecure SVG handling</h2>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="701" height="400" src="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/2-14.webp" alt="Potential consequences of insecure SVG handling" class="wp-image-30899" srcset="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/2-14.webp 701w, https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/2-14-300x171.webp 300w" sizes="auto, (max-width: 701px) 100vw, 701px" /></figure>



<p>The fallout can be incredibly serious when SVGs slip through without the proper checks. A single compromised icon or illustration can infect anyone who uses the app, leading to stolen credentials, infected devices, and hijacked sessions. </p>



<p>For organizations, it’s even more serious. Projects and deliverables can be delayed, and client trust can be eroded. Your entire brand could face long-term reputational damage if its platform is linked to malicious content.&nbsp;</p>



<p>Insecure SVG handling also opens the door for much broader frontend vulnerabilities. Particularly, when scripts interact with other parts of an application. Even teams under tight deadlines can’t afford to make security an afterthought.</p>



<h2 class="wp-block-heading">Steps designers and teams can take to stay safe</h2>



<p>Despite the risks involved, designers and engineers can take practical steps to protect their projects.</p>



<ul class="wp-block-list">
<li>Always sanitize files before use. Use trusted libraries and tools to strip out elements like &lt;script&gt;, onload, or &lt;foreignObject&gt; tags. If assets come from unverified sources, convert them to safer formats before adding them to your project.</li>



<li>Establish clear guidelines with your team for obtaining assets. Only use icon packs and illustrations from vetted repositories or <a href="https://docs.oracle.com/cd/F26413_49/books/DataQAdm/c-Vendor-Libraries-hz1031357.html" target="_blank" rel="noreferrer noopener nofollow">vendor libraries</a>. Automating some of these checks within the build pipeline can lower the risk of unsafe assets slipping through.</li>



<li>During collaboration, treat SVGs like you would any other code. Always review and scan them first. Never assume they’re harmless.&nbsp;</li>
</ul>



<p>Adopting these habits enables design and product teams to protect their workflow and users. Small, consistent efforts can help stop hidden malware from reaching the public.</p>



<h2 class="wp-block-heading">Best practices in design ops and collaboration</h2>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="701" height="400" src="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/3-14.webp" alt="Best practices in design ops and collaboration" class="wp-image-30903" srcset="https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/3-14.webp 701w, https://octet-gatsby.in2.cdn-alpha.com/wp-content/uploads/2025/09/3-14-300x171.webp 300w" sizes="auto, (max-width: 701px) 100vw, 701px" /></figure>



<p>Securing SVGs doesn’t stop with the design team. Design ops leaders need to set internal policies that govern <a href="https://www.adobe.com/in/creativecloud/file-types/image/vector/svg-file.html" target="_blank" rel="noreferrer noopener nofollow">SVG usage</a>. Automating scans into build pipelines can help enforce those core rules without slowing the workflow. </p>



<p>It’s also critical to educate designers and developers about how SVG malware works. A quick review can reveal red flags before assets are shared publicly.&nbsp;</p>



<p>When teams work across offices or remotely, they must also secure their communication channels. Encrypting asset transfers through secure platforms or VPNs prevents tampering. </p>



<p>Compared with the damage from a breach, <a href="https://nordvpn.com/blog/how-much-does-a-vpn-cost/" target="_blank" rel="noreferrer noopener">VPN cost</a> and similar investments are minimal. Treating SVGs as part of the broader security posture keeps projects safe and clients confident.</p>



<h2 class="wp-block-heading">Conclusion</h2>



<p>SVGs will be a part of product design for the foreseeable future. Their flexibility and efficiency make them incredibly valuable assets. That said, their code-based nature means they need more consideration than regular images. Malware hidden in an SVG can compromise images, apps, websites, and ultimately, user trust.&nbsp;</p>



<p>Sanitizing files, enforcing secure workflows, and facilitating secure collaboration can reduce risks. Above all, be sure to invest in reliable tools, from sanitizers to VPNs. Safer SVG handling will undoubtedly lead to stronger, more resilient products for everyone.&nbsp;</p>
