CVE-2023-4376 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. The Serial Codes Generator and Validator with WooCommerce Support WordPress plugin before 2.4.15 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup). EPSS estimates a 0.40% chance of exploitation in the next 30 days.
