CVE-2024-11782 – WP Mailster <= 1.8.17.0 - Authenticated (Contributor+) Stored Cross-Site Scripting

https://notcve.org/view.php?id=CVE-2024-11782

The WP Mailster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'mst_subscribe' shortcode in all versions up to, and including, 1.8.17.0 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/browser/wp-mailster/tags/1.8.17.0/mailster/subscr/SubscriberPlugin.php#L216 https://plugins.trac.wordpress.org/changeset/3198497/wp-mailster/trunk/mailster/subscr/SubscriberPlugin.php https://www.wordfence.com/threat-intel/vulnerabilities/id/909beed4-06a9-4ec4-bf00-4072a38af82b?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
