What the vulnerability does
01Description
The Cost of Goods: Product Cost & Profit Calculator for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'alg_wc_cog_product_cost' and 'alg_wc_cog_product_profit' shortcodes in all versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
