Fix SVG Upload Not Working After Shopware 6.7.10.0 Update

After updating to Shopware 6.7.10.0, some users may experience an issue where SVG file uploads or generation stop working in the media library or during theme/content uploads.

This issue is related to updated SVG security handling introduced in newer Shopware versions.

Affected Environment

• Shopware 6.7.10.0 and above
• Media Manager / File Uploads
• SVG file uploads in admin or storefront assets

Issue Description

After the latest Shopware update:

• SVG files fail to upload
• SVG rendering or generation is blocked
• Upload process may silently fail or be rejected
• No clear error may be shown in the admin panel

This happens due to stricter SVG sanitization rules introduced for security improvements.

Root Cause

Shopware 6.7.10.0 enforces tighter restrictions on SVG files to prevent malicious scripts or unsafe elements inside SVGs.

By default, only a limited set of:

• SVG elements
• Attributes
• Reference attributes

are allowed.

Any custom or non-whitelisted SVG content gets blocked during upload or processing.

Solution

If you need to allow additional SVG elements or attributes, you can extend the allowlist in your Shopware configuration.

Step 1: Update Configuration

Edit the following file:

Step 2: Add Allowed SVG Rules

Add or extend the configuration as shown below:

Step 3: Clear Cache

After updating the configuration, run:

Then re-test SVG upload.

Important Notes

• Only allow trusted SVG elements and attributes
• Avoid enabling unsafe or script-related SVG features
• This change is intended to improve system security

Need Help

If SVG uploads still fail after applying the configuration, it may be related to:

• Theme/plugin overrides
• Custom media processing logic
• Server-level file restrictions
