CVE-2025-69370Network attack vector

Unauthenticated PHP object injection via unsafe deserialization

Published Feb 20, 2026 · Updated Feb 20, 2026

PHP object injection in ThemeGoods Capella 2.5.5 and earlier allows remote attackers to inject arbitrary PHP objects via untrusted serialized input. Neither the CNA record nor the cited vulnerability entry identifies the affected function or request parameter; the disclosed mechanism is unsafe deserialization of attacker-controlled data. Exploitation requires no authentication, but file deletion, sensitive-data retrieval, or code execution additionally requires a usable POP chain from another installed plugin or theme because Capella contains no known chain.
