Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Path Traversal: Five separate fixes address directory traversal in different operations (group actions, upload, search/backup, general path cleaning), indicating a systemic lack of centralized path sanitization. Each fix patches a specific sink, leaving other paths potentially vulnerable.

Remote Code Execution: Critical RCE via file upload from URL and stat command injection. Mitigation relies on extension allowlist and shell argument escaping, which must be enforced on all file operations that invoke shell commands.

CSRF: State-changing operations (copy, rename, delete, zip, unzip, chmod) lacked proper CSRF token enforcement; fix added die() after failed verification. All such operations must consistently call verifyToken.
