Post Grid permits unauthenticated WordPress hook execution
Post Grid exposes several functions in includes/blocks/form-wrap/function.php to unauthenticated hook injection. An attacker can invoke WordPress actions where the selected hook lacks its own security control. The authoritative description says versions 2.2.32 through 2.3.1 are affected, while its machine-readable affected range says 2.2.85 through 2.3.32; that source inconsistency remains unresolved.
