CVE-2023-5237 – Memberlite Shortcodes < 1.3.9 - Contributor+ Stored XSS via Shortcode

https://notcve.org/view.php?id=CVE-2023-5237

The Memberlite Shortcodes WordPress plugin before 1.3.9 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admin. El complemento Memberlite Shortcodes de WordPress anterior a 1.3.9 no valida ni escapa algunos de sus atributos de shortcode antes de devolverlos a la página, lo que podría permitir a los usuarios con un rol tan bajo como colaborador realizar ataques de Cross-Site Scripting almacenados que podrían usarse contra usuarios con altos privilegios como administrador. The Memberlite Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions up to, and including, 1.3.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://research.cleantalk.org/cve-2023-5237-memberlite-shortcodes-stored-xss-via-shortcode https://wpscan.com/vulnerability/a46d686c-6234-4aa8-a656-00a65c55d0b0 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
