CVE-2025-14420
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on systems running vulnerable versions of pdfforge PDF Architect by tricking users into opening malicious CBZ files. The flaw exists in how the software handles file paths during CBZ parsing, enabling directory traversal attacks. Users who open untrusted CBZ files with affected PDF Architect installations are at risk.
💻 Affected Systems
- pdfforge PDF Architect
📦 What is this software?
Pdf Architect by Pdfforge
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the current user, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Limited user-level code execution allowing file system access, credential harvesting, and lateral movement within the network from the compromised user's context.
If Mitigated
No impact if proper application whitelisting, file type restrictions, or sandboxing prevents malicious CBZ execution.
🎯 Exploit Status
Exploitation requires user interaction but uses common directory traversal techniques; weaponization likely due to RCE potential and user-targeting vectors.
🛠️ Fix & Mitigation
✅ Official Fix
