{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/73724?format=json","vulnerability_id":"VCID-k89x-npbh-ukhe","summary":"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.","aliases":[{"alias":"CVE-2026-4088"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-4088","reference_id":"","reference_type":"","scores":[{"value":"0.00027","scoring_system":"epss","scoring_elements":"0.0821","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-4088"},{"reference_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/19a3fc90-b81c-4451-80e0-cead99a2dcd9?source=cve","reference_id":"19a3fc90-b81c-4451-80e0-cead99a2dcd9?source=cve","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/19a3fc90-b81c-4451-80e0-cead99a2dcd9?source=cve"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L14","reference_id":"box_display_template.php#L14","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L14"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L14","reference_id":"box_display_template.php#L14","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L14"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L18","reference_id":"box_display_template.php#L18","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L18"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L18","reference_id":"box_display_template.php#L18","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L18"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L2","reference_id":"box_display_template.php#L2","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/box_display_template.php#L2"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L2","reference_id":"box_display_template.php#L2","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/box_display_template.php#L2"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/shortcode_setup.php#L8","reference_id":"shortcode_setup.php#L8","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-23T13:41:45Z/"}],"url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/tags/1.1/inc/shortcode_setup.php#L8"},{"reference_url":"https://plugins.trac.wordpress.org/browser/switch-cta-box/trunk/inc/shortcode_setup.php#L8","reference_id":"shortcode_setup.php#L8","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scor
