Easy Social Photos Gallery Mif
Monthly
Stored cross-site scripting (XSS) in Easy Social Photos Gallery - MIF plugin for WordPress (versions up to 3.1.2) allows authenticated attackers with contributor-level access to inject arbitrary HTML and JavaScript via the 'wrapper_class' shortcode attribute of the 'my-instagram-feed' shortcode. The vulnerability exists because the plugin uses sanitize_text_field() instead of esc_attr() when outputting the attribute inside HTML class tags, allowing attackers to break out of the attribute context and inject event handlers that execute in users' browsers when they visit affected pages.
