CVE-2023-0232Network attack vector

Unauthenticated object injection via tracking cookie

Published Feb 21, 2023 · Updated Mar 12, 2025

PHP object injection in HasThemes ShopLentor before 2.5.4 allows remote attackers to inject objects through a crafted cookie. The woolentor_set_views_count function passes the user-controlled cookie value to PHP unserialize without validating its contents. No authentication or user interaction is required, but file deletion, data retrieval, or code execution requires a usable POP chain from another installed plugin or theme.
