# CVE-2026-120206: Thelia before 3.2.0 Back-Office CSRF via URL Token and Unprotected Actions

Status: published. Published: 2026-10-31. Updated: 2026-11-02.

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.
