Technical details
A stored XSS vulnerability exists in the Divi theme's Social Media Follow module via the `skype_url` shortcode attribute. The root cause is a three-part sanitization failure: (1) the `skype_url` field is not included in the `$url_options` whitelist, preventing invocation of `esc_url_raw()` during shortcode processing, (2) the render code explicitly skips `esc_url()` for Skype URLs, and (3) only `sanitize_text_field()` is applied, which preserves quote characters enabling attribute breakout. The unsanitized value is interpolated directly into a single-quoted `href` attribute. An authenticated attacker with Contributor-level access or above can inject arbitrary JavaScript that executes whenever users interact with the injected element. The vulnerability affects Divi versions up to and including 4.27.6 and has been patched in version 4.27.7.
