CVE-2025-13713
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code as root on systems running vulnerable versions of Tencent Hunyuan3D-1. Attackers can exploit this by tricking users into visiting malicious web pages or opening malicious files. The vulnerability affects installations where the load_pretrained function processes untrusted data.
💻 Affected Systems
- Tencent Hunyuan3D-1
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root-level code execution, leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Attacker gains initial foothold with root privileges, enabling lateral movement, credential harvesting, and deployment of additional malware.
If Mitigated
Attack fails due to proper input validation or restricted execution environment, resulting in denial of service at most.
🎯 Exploit Status
User interaction required (visiting malicious page or opening malicious file). The ZDI advisory suggests exploit development is feasible given the deserialization flaw.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 454284503670312d4e06f6251c9be2f9f6d0fae7 and later
Vendor Advisory: https://github.com/Tencent-Hunyuan/Hunyuan3D-1/commit/454284503670312d4e06f6251c9be2f9f6d0fae7
Restart Required: Yes
Instructions:
1. Update to the latest version of Hunyuan3D-1 from the official GitHub repository. 2. Replace the vulnerable load_pretrained function implementation with the patched version. 3. Restart any services or applications using Hunyuan3D-1.
🔧 Temporary Workarounds
Input Validation Wrapper
allImplement strict input validation before passing data to load_pretrained function
# Custom validation logic required based on application
Network Segmentation
allIsolate systems running Hunyuan3D-1 from untrusted networks
# Use firewall rules to restrict network access
🧯 If You Can't Patch
- Implement strict file integrity monitoring on Hunyuan3D-1 installation directories
- Deploy application allowlisting to prevent execution of unauthorized code
🔍 How to Verify
Check if Vulnerable:
Check if your Hunyuan3D-1 version includes commit 454284503670312d4e06f6251c9be2f9f6d0fae7. If not, you are vulnerable.Check Version:
git log --oneline | grep -i "4542845" or check version metadata in the softwareVerify Fix Applied:
Verify the load_pretrained function includes proper input validation and safe deserialization practices.📡 Detection & Monitoring
