| Explanation | a remote HTTP fetch (`wp_remote_*` / `curl_exec`) is followed by `@unserialize` within the same file — classic PHP Object Injection C2 gadget. The error-suppressed form is the tell: legit code wants to know when deserialize fails; attackers suppress so malformed gadgets do not leak. A real finding regardless of author intent: any plugin that deserializes remote responses without validation is a latent RCE chain if the remote endpoint is ever compromised. |
