    Title
    Simple CAPTCHA with Cloudflare Turnstile <= 1.44.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes
    Summary
    The Simple CAPTCHA with Cloudflare Turnstile plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the [gravity-simple-turnstile] shortcode in versions up to, and including, 1.44.3 This is due to insufficient input sanitization and output escaping on the shortcode attribute in the cfturnstile_gravity_shortcode() function: the value is filtered only by esc_html() and sanitize_text_field() (neither of which touches parentheses or dots) and then emitted via esc_js() in a raw JavaScript expression context outside any string literal (esc_js only escapes quotes, backslashes, and newlines). 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.
