From e2d91930cf9dcaf3975bd6196716578562c840f0 Mon Sep 17 00:00:00 2001 From: liushanggui <> Date: Sun, 22 Feb 2026 10:34:33 +0800 Subject: [PATCH 1/2] fix(security): prevent RCE and command injection vulnerabilities Critical fixes: 1. RCE via install script download (commands.rs) - Download script to temp file first - Verify SHA256 checksum before execution - Prevents MITM attacks on install.sh 2. Command injection in exec_login (ssh.rs) - Sanitize target_bin to allow only safe characters - Shell-quote commands for safe interpolation - Replace unsafe eval with pipe to stdin Added sha2 dependency for checksum verification.
