ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

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.
