CVE-2025-69404Network attack vector

Unauthenticated object injection via untrusted deserialization

Published Feb 20, 2026 · Updated Feb 20, 2026

PHP object injection in ThemeREX Extreme Store 1.5.10 and earlier allows remote attackers to inject objects through untrusted serialized input. Public advisories state that the theme deserializes attacker-controlled data but do not identify the affected function, parameter, or request path. Exploitation requires no authentication; harmful file deletion, data disclosure, or code execution additionally requires a usable POP chain supplied by another installed plugin or theme.
