A vulnerability classified as problematic was found in j2commerce J2Store Extension up to 3.3.2/4.0.22/4.1.7. This vulnerability affects the function saveAddress of the component Cart/Checkout/Myprofile Controllers. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect integrity. CVE summarizes:

Joomla Extension - j2commerce.com - Missing CSRF protection on cart, checkout and myprofile controllers in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - A forged request riding a victim's active checkout session could silently overwrite the billing or shipping address before order confirmation — the most consequential sub-case, since it opens the door to redirecting a paid order's goods to an attacker-controlled address — or tamper with a saved profile address via `saveAddress()`. As before, each forged request executes with only the victim's own session privileges, so there is no cross-account data access.
