description

ACF Extended PRO through version 0.9.2.6 can allow unauthenticated requests to invoke WordPress functions with attacker-controlled arguments during field rendering. Exposure requires either shortcode_preview to be enabled for the affected form or an environment where OpenSSL functions are unavailable.

mitigation

Keep shortcode_preview disabled and ensure the server has working OpenSSL support. Disable or restrict access to affected forms, or remove the plugin, until a vendor-fixed release is available.
