CVE-2026-4088

CVSS v3.1

6.4

Medium

AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
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.
