CVE-2024-12312Network attack vector

Unauthenticated PHP object injection via cookie deserialization

Published Dec 12, 2024 · Updated Apr 8, 2026

PHP object injection in John Weissberg Print Science Designer 1.3.152 and earlier allows remote attackers to inject objects via a cookie. The saved-project handler in includes/saved-projects.php passes the attacker-controlled designer-saved-projects cookie into PHP deserialization without restricting object creation. Exploitation needs no account, but file deletion, data retrieval, or code execution requires a usable POP chain from another installed plugin or theme.
