The CozyStay theme for WordPress is vulnerable to PHP Object Injection in versions up to 1.7.1 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object.
No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 1.7.1, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
