Summary
Thelia versions through 2.6.0 contain an open redirect in the address creation workflow. After a user submits the Add New Address form from a crafted URL, the application redirects to the URL in the next parameter without checking that it belongs to the same origin or an approved allowlist (CWE-601). A remote attacker with no privileges can supply an external URL and send users to a website they control, which requires user interaction.

Description from the CNA
Thelia v2.6.0 contains an open redirect vulnerability in its address creation workflow. After a user accesses a crafted URL and successfully submits the “Add New Address” form, the application redirects them to the URL specified in the `next` parameter. Because the application does not validate whether the destination belongs to the same origin or an approved allowlist, an attacker can supply an arbitrary external URL and redirect users to an attacker-controlled website.
