CVE-2024-37099Public exploitNetwork attack vector

Unauthenticated code execution via serialized donor title

Published Aug 19, 2024 · Updated Apr 28, 2026

PHP object injection in StellarWP GiveWP 3.14.1 and earlier allows remote attackers to execute code through a crafted donor title. The donation form validator omits give_title from serialized-field checks, and donor-meta retrieval later unserializes that value so a bundled POP chain reaches shell_exec. An unauthenticated request to a published donation form is sufficient; the same object path can also delete arbitrary server files.
