CVE-2026-7421 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionThe Passeum Ticketing plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.0. This is due to the `get_shop_url()` method returning the `shop_name` setting value without sanitization when it begins with "http", combined with insufficient validation in the `validate_shop_name()` function which only checks for empty values and string type. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary external scripts by setting the `shop_name` to an attacker-controlled URL (e.g., `https://attacker.com`), which causes the plugin to enqueue external JavaScript and CSS from the attacker-controlled domain via `wp_register_script()` and `wp_register_style()`. The injected scripts execute on every frontend page containing any Passeum Ticketing shortcode, affecting all site visitors. Please note that this does not affect single-site installations as administrators already have the `unfiltered_html` capability. Metrics
