CVE-2026-27082Network attack vector

Unauthenticated object injection via untrusted deserialization

Published Mar 25, 2026 · Updated Mar 25, 2026

PHP object injection in ThemeREX Love Story 1.3.12 and earlier allows remote attackers to inject objects via untrusted serialized input. Public records do not identify the affected function or input field, but state that theme code deserializes attacker-controlled data into PHP objects. No known POP chain exists in the theme itself; file deletion, sensitive-data retrieval, or code execution requires a usable gadget chain from another installed plugin or theme.
