{"id":"CVE-2026-7421","state":"PUBLISHED","title":"Passeum Ticketing <= 1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'shop_name' Setting","description":"The 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.","publishedAt":"2026-06-02T23:27:48.373Z","updatedAt":"2026-06-03T14:07:40.856Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["passeum Passeum Ticketing"],"affected":[{"vendor":"passeum","product":"Passeum Ticketing","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/48363f1f-dae8-4efa-824f-098550245ca3?source=cve","https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/passeum-ticketing.php#L202","https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/passeum-ticketing.php#L202","https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/passeum-ticketing.php#L40","https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/passeum-ticketing.php#L40","https://plugins.trac.wordpress.org/browser/passeum-ticketing/tags/1.0/inc/settings.php#L141","https://plugins.trac.wordpress.org/browser/passeum-ticketing/trunk/inc/settings.php#L141"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/7xxx/CVE-2026-7421.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-7421","state":"PUBLISHED","datePublished":"2026-06-02T23:27:48.373Z","dateUpdated":"2026-06-03T14:07:40.856Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-29T14:25:19.682Z"},"containers":{"cna":{"title":"Passeum Ticketing <= 1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'shop_name' Setting","descriptions":[{"lang":"en","value":"The Passeum Ticketing plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.0.
