Descriptions

The Smash Balloon Social Post Feed WordPress plugin before 4.1.6 does not validate and escapes some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as a contributor to perform Stored Cross-Site Scripting attacks against logged-in admins.

El complemento Smash Balloon Social Post Feed de WordPress anterior a 4.1.6 no valida ni escapa algunos de sus atributos de código corto 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 entre administradores conectados.

The Smash Balloon Social Post Feed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode in versions up to, and including, 4.1.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
