CVE-2026-78081 Details
Description
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.
A vulnerability exists in the J2Store extension for Joomla, specifically in versions 1.0.0 through 3.3.2, 4.0.0 through 4.0.22, and 4.1.0 through 4.1.7. The issue arises from a lack of Cross-Site Request Forgery (CSRF) protection on the cart, checkout, and my profile controllers. This vulnerability allows a forged request to exploit an active checkout session, potentially overwriting the billing or shipping address before order confirmation. Such an action could redirect goods from a paid order to an address controlled by an attacker. Additionally, the vulnerability could be used to tamper with saved profile addresses through the 'saveAddress()' function. Each forged request would be executed with the victim's session privileges, preventing cross-account data access.
