The SVG Block WordPress plugin before 1.1.20 does not sanitize SVG file contents, which enables users with at least the author role to SVG with malicious JavaScript to conduct Stored XSS attacks.
El complemento SVG Block WordPress anterior a la versión 1.1.20 no sanitiza el contenido del archivo SVG, lo que permite a los usuarios con al menos el rol de autor de SVG con JavaScript malicioso realizar ataques XSS almacenados.
The SVG Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.1.19 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
