The Ad Inserter for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.7.30 via the ai-debug-processing-fe URL parameter. This can allow unauthenticated attackers to extract sensitive data including installed plugins (present and active), active theme, various plugin settings, WordPress version, as well as some server settings such as memory limit, installation paths.

The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings (the backup path parameter) in versions up to, and including, 0.9.89 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The WP Mailto Links – Protect Email Addresses plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'wpml_mailto' shortcode in versions up to, and including, 3.1.3 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. This was partially patched in version 3.1.3 and fully patched in version 3.1.4.

The Horizontal scrolling announcement plugin for WordPress is vulnerable to SQL Injection via the plugin's [horizontal-scrolling] shortcode in versions up to, and including, 9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with subscriber-level and above permissions to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Poptin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'poptin-form' shortcode in versions up to, and including, 1.3 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.

The Social Media Share Buttons & Social Sharing Icons plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.8.5 via the sfsi_save_export function. This can allow subscribers to export plugin settings that include social media authentication tokens and secrets as well as app passwords.
