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."}],"title":"Passeum Ticketing <= 1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'shop_name' Setting","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/48363f1f-dae8-4efa-824f-098550245ca3?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/passeum-ticketing.php#L202"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/passeum-ticketing.php#L202"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/passeum-ticketing.php#L40"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/passeum-ticketing.php#L40"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/inc/settings.php#L141"},{"url":"https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/inc/settings.php#L141"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","baseScore":4.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"KEVIN LEE"}],"timeline":[{"time":"2026-06-02T10:57:01.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-03T13:18:04.431808Z","id":"CVE-2026-7421","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-03T14:07:40.856Z"}}]}}
