{"id":"CVE-2026-4088","state":"PUBLISHED","title":"Switch CTA Box <= 1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode","description":"The Switch CTA Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wppw_cta_box' shortcode in all versions up to, and including, 1.1. This is due to insufficient input sanitization and output escaping on user-supplied post meta values including 'cta_box_button_link', 'cta_box_button_id', 'cta_box_button_text', and 'cta_box_description'. The shortcode reads post meta from a user-specified post ID and echoes these values directly into HTML output without any escaping functions (no esc_attr(), esc_url(), or esc_html()). 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":"2026-04-22T07:45:31.826Z","updatedAt":"2026-04-23T13:42:30.311Z","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":["wpshouter Switch CTA Box"],"affected":[{"vendor":"wpshouter","product":"Switch CTA Box","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/19a3fc90-b81c-4451-80e0-cead99a2dcd9?source=cve","https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L18","https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L18","https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L14","https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L14","https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L2","https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L2","https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/shortcode_setup.php#L8","https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/shortcode_setup.php#L8"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4088.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4088","state":"PUBLISHED","datePublished":"2026-04-22T07:45:31.826Z","dateUpdated":"2026-04-23T13:42:30.311Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T21:01:55.593Z"},"containers":{"cna":{"title":"Switch CTA Box <= 1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode","descriptions":[{"lang":"en","value":"The Switch CTA Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wppw_cta_box' shortcode in all versions up to, and including, 1.1.
