This is due to insufficient input sanitization and output escaping on the 'title' attribute of the 'sherkcptdisplays' shortcode. Specifically, in the sherkcptdisplays_func() function in includes/SherkCPTDisplaysShortcode.php, the 'title' attribute value is extracted from shortcode_atts() on line 19 and directly concatenated into an HTML <h2> tag on line 31 without any escaping. 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."}, {"lang": "es", "value": "El plugin Sherk Custom Post Type Displays para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s del atributo 'title' del shortcode en todas las versiones hasta la 1.2.1, inclusive.

Espec\u00edficamente, en la funci\u00f3n sherkcptdisplays_func() en includes/SherkCPTDisplaysShortcode.php, el valor del atributo 'title' se extrae de shortcode_atts() en la l\u00ednea 19 y se concatena directamente en una etiqueta HTML en la l\u00ednea 31 sin ning\u00fan escape.
