Description

Thelia before 3.2.0 contains a cross-site request forgery vulnerability in the back office that allows attackers to forge administrative actions because per-session CSRF tokens leak via URL query strings. Attackers can reuse leaked tokens or target the unprotected setToggleVisibilityAction and updatePositionAction to make logged-in administrators delete, hide or reorder catalogue and configuration objects.
