CVE-2026-39292Network attack vector

Unauthenticated code execution via unrestricted file upload

Published May 29, 2026 · Updated May 29, 2026

Unrestricted file upload in Falco Solutions PHPPageBuilder 0.31.0 allows remote attackers to execute code through the pagemanager/pagebuilder module. The module accepts uploaded files without adequately validating file types or rejecting executable content, permitting server-side execution. Network access is sufficient; no authentication or user interaction is required, and successful exploitation runs arbitrary code on the server.
