Descriptions

The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG file upload in all versions up to, and including, 2.6.8 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 an injected page.

The Otter Blocks – Gutenberg Blocks, Page Builder para Gutenberg Editor y el complemento FSE para WordPress son vulnerables a Cross-Site Scripting a través de la carga de archivos SVG en todas las versiones hasta la 2.6.8 incluida debido a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso a nivel de autor y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
