Welcart product field permits Author stored XSS
Welcart e-Commerce before 2.11.34 lets an Author store script-bearing content in the product-name field exposed as itemName and getItemName(). Multiple product-facing output paths render the stored name without contextual escaping, so a visitor viewing the affected product executes the script. Version 2.11.34 applies esc_html(), esc_attr() and esc_js() at the remaining product-name sinks. The exact editor POST parameter and reporter's specific page template are not disclosed.
