      <title>CVE-2026-78064 — Joomla Extension - j2commerce.com - Anonymous cart-record tampering via inherited FOF `save` task in J2Store 1.0.0-3.3.…</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-78064</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; j2commerce.com J2Store extension for Joomla&lt;/p&gt;
&lt;p&gt;Joomla Extension - j2commerce.com - Anonymous cart-record tampering via inherited FOF `save` task in J2Store 1.0.0-3.3.21, 4.0.0-4.0.21, 4.1.0-4.1.6 - `fof.xml` grants the `carts` view&amp;#39;s tasks a wildcard `true` ACL, and FOF only enforces CSRF tokens on back-end HTML requests, not on front-end `format=raw` requests. `J2StoreControllerCarts` already scoped `remove()` to the caller&amp;#39;s own session, but never overrode the generic FOF `save` task, so it remained reachable to insert new cart rows with an attacker-chosen `user_id`/`session_id`, or overwrite an existing row by id.&lt;/p&gt;</description>
