CVE-2026-55062: uniget CLI has Path Traversal in Hook Files - Directory Escape Vulnerability

August 17, 2026

Path Traversal vulnerability in hook filename handling allows attackers to access and manipulate arbitrary files outside the hooks directory via directory escape sequences like passwd.

Details File: hooks.go Lines 135-160

hookFileName := args[0]  // User input not validated
hookFile = preInstallHooksDir + "/" + hookFileName  // Direct concatenation

Hook filenames are concatenated directly without sanitizing ../ sequences, allowing directory traversal.
