{"id":"CVE-2026-9635","state":"PUBLISHED","title":"WP Shortcode by MyThemeShop <= 1.4.17 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute","description":"The WP Shortcode by MyThemeShop plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' parameter of the [tab] shortcode in versions up to, and including, 1.4.17. This is due to insufficient input sanitization and output escaping in the mts_tabs() function, which outputs the title shortcode attribute directly into the HTML output between anchor tags without applying any escaping functions. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-07-23T06:52:34.356Z","updatedAt":"2026-07-23T14:01:09.824Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["mythemeshop WP Shortcode by MyThemeShop"],"affected":[{"vendor":"mythemeshop","product":"WP Shortcode by MyThemeShop","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.17","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6f3bcf70-2900-4a13-9ed4-264a15af9725?source=cve","https://plugins.trac.wordpress.org/browser/wp-shortcode/trunk/wp-shortcode.php#L774","https://plugins.trac.wordpress.org/browser/wp-shortcode/trunk/wp-shortcode.php#L766"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9635.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9635","state":"PUBLISHED","datePublished":"2026-07-23T06:52:34.356Z","dateUpdated":"2026-07-23T14:01:09.824Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-26T17:55:37.764Z"},"containers":{"cna":{"title":"WP Shortcode by MyThemeShop <= 1.4.17 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute","descriptions":[{"lang":"en","value":"The WP Shortcode by MyThemeShop plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' parameter of the [tab] shortcode in versions up to, and including, 1.4.17.
