CVE-2026-24806
📋 TL;DR
This CVE describes a code injection vulnerability in the quick-media library's SVG plugin when processing PNG files. Attackers can execute arbitrary code by crafting malicious PNG images. This affects all applications using quick-media versions before 1.0 that process untrusted PNG files.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the PNG file, potentially leading to complete system compromise.
Likely Case
Application crash or denial of service when processing malicious PNG files, with potential for limited code execution depending on context.
If Mitigated
No impact if the application doesn't process untrusted PNG files or has proper input validation in place.
🎯 Exploit Status
Exploitation requires crafting malicious PNG files and getting them processed by vulnerable systems. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.0
Vendor Advisory: https://github.com/liuyueyi/quick-media/pull/122
Restart Required: Yes
Instructions:
1. Update quick-media dependency to version 1.0 or later. 2. Rebuild and redeploy affected applications. 3. Restart services using the updated library.
🔧 Temporary Workarounds
Disable SVG plugin PNG processing
allRemove or disable the batik-codec-fix module if PNG processing via SVG plugin is not required
Remove dependency: org.apache.batik:batik-codec from build configuration
Input validation for PNG files
allImplement strict validation of PNG file inputs before processing
Implement file signature validation and size limits in application code
🧯 If You Can't Patch
- Implement network segmentation to isolate vulnerable systems
- Deploy WAF rules to block suspicious PNG uploads
🔍 How to Verify
Check if Vulnerable:
Check if your application uses quick-media version <1.0 and processes PNG files through the SVG pluginCheck Version:
Check Maven/Gradle dependencies for 'com.github.liuyueyi:quick-media' versionVerify Fix Applied:
Verify quick-media dependency is updated to version 1.0 or later in your build configuration📡 Detection & Monitoring
Log Indicators:
- Java stack traces mentioning PNGImageEncoder
- Unexpected application crashes during PNG processing
- Unusual file upload patterns
Network Indicators:
- Large PNG file uploads to vulnerable endpoints
- Multiple failed PNG processing attempts
