CVE-2026-1781 (GCVE-0-2026-1781)
Vulnerability from cvelistv5 – Published: 2026-03-11 01:22 – Updated: 2026-04-08 16:35

Title
MC4WP: Mailchimp for WordPress <= 4.11.1 - Missing Authorization to Unauthenticated Arbitrary Subscription Deletion
Summary
The MC4WP: Mailchimp for WordPress plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 4.11.1. This is due to the plugin trusting the `_mc4wp_action` POST parameter without validation, allowing unauthenticated attackers to force the form to process unsubscribe actions instead of subscribe actions. This makes it possible for unauthenticated attackers to arbitrarily unsubscribe any email address from the connected Mailchimp audience via the `_mc4wp_action` parameter, granted they can obtain the form ID (which is publicly exposed in the HTML source).

Title
Social Sharing (by Danny) <= 1.3.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode
Summary
The Social Sharing (by Danny) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'dvk_social_sharing' shortcode in all versions up to, and including, 1.3.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

MC4WP: Mailchimp Top Bar <= 1.6.0 - Reflected Cross-Site Scripting

MailChimp for Wordpress <= 4.9.16 - Authenticated (Administrator+) Stored Cross-Site Scripting
Summary
The MC4WP: Mailchimp for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.9.16 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.

Title
MC4WP: Mailchimp for WordPress 4.9.9 - 4.9.16 - Reflected Cross-Site Scripting
Summary
The MC4WP: Mailchimp for WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'email' parameter when a placeholder such as {email} is used for the field in versions 4.9.9 to 4.9.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
