CVE-2026-40760Network attack vector

Unauthenticated PHP object injection

Published Jun 16, 2026 · Updated Jun 16, 2026

PHP object injection in Edge Themes Behold 1.5 and earlier allows remote attackers to inject PHP objects without authentication. The CNA and vendor advisory do not identify the request parameter, PHP call, or code path that deserializes untrusted data. Exploitation requires no account, but public evidence establishes object injection rather than a specific code-execution or data-impact outcome.
