From 231e8464d93cd1a1f839db4b963e119a2828b3e6 Mon Sep 17 00:00:00 2001 From: TheFlow Date: Tue, 14 Oct 2025 18:03:56 +1300 Subject: [PATCH] feat: complete file security testing with production-ready malware detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented and tested comprehensive file upload security pipeline with automatic quarantine system. Added ClamAV fallback for development environments and resolved cross-filesystem quarantine issues.
