JTL-Shop vulnerabilities

A vulnerability in JTL-Shop's authentication middleware processes the plugin safe mode toggle on the admin logout route before checking authentication. An unauthenticated attacker can toggle the safe mode, deactivating all plugins and causing a shop-wide denial of service.

The public consent endpoint of JTL-Shop accepts arbitrary consent names from unauthenticated visitors without validating them against the configured consent items. These names are stored in the consent statistics and rendered without output encoding in the administration backend, allowing script code injection that executes in an administrator's browser session.

JTL Shop versions 5.2.0 through 5.7.1 contain a server-side template injection vulnerability that allows unauthenticated attackers to inject malicious template syntax due to unsanitized user-supplied input passed to the Smarty template engine.
