While the function supports secure loading for .skops models, it falls back to the joblib loader for non-.zip file formats without any warning. This is problematic as joblib <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-47168-use-after-free-vulnerability-in-microsoft-office-word-allowing-unauthorized-code-execution\/\"  data-wpil-monitor-id=\"73110\">allows arbitrary code<\/a> execution during loading, bypassing the security measures in place.

An attacker could craft a malicious non-.zip file that contains a payload <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-30327-integer-overflow-vulnerability-in-incopy-leading-to-potential-arbitrary-code-execution\/\"  data-wpil-monitor-id=\"73549\">leading to arbitrary code<\/a> execution when loaded by the joblib loader.<\/p>\n<pre><code class=\"\" data-line=\"\">from skops import Card\n# Malicious payload embedded in a non-zip file\nmalicious_file = &#039;malicious.pkl&#039;\n# Loading the malicious file using the Card.get_model function\nmodel = Card.get_model(malicious_file)<\/code><\/pre>\n<p>In this example, `malicious.pkl` is a non-zip file containing a crafted payload.
