CVE-2024-48042Network attack vector

Administrator-level command execution via unsafe deserialization

Published Oct 16, 2024 · Updated Apr 28, 2026

Unsafe deserialization in Contact Form by Supsystic 1.7.28 and earlier allows remote authenticated users to execute server commands. The CNA labels the flaw untrusted deserialization, while the upstream changelog describes SSTI; neither source identifies the affected function or unsafe operation. Administrator-level WordPress access is required; successful exploitation runs attacker-controlled commands with the web server's privileges.
