https://notcve.org/view.php?id=CVE-2024-8628

The Popup, Optin Form & Email Newsletters for Mailchimp, HubSpot, AWeber – MailOptin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'post-meta' shortcode in all versions up to, and including, 1.2.70.3 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. • https://plugins.trac.wordpress.org/changeset/3152552/mailoptin/trunk/src/core/src/EmailCampaigns/Shortcodes.php https://www.wordfence.com/threat-intel/vulnerabilities/id/4d64253b-5803-470d-81ba-d5629406b019?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
