The Newsletters plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's newsletters_video shortcode in all versions up to, and including, 4.9.9.4 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/3175816 https://wordpress.org/plugins/newsletters-lite/#developers https://www.wordfence.com/threat-intel/vulnerabilities/id/915c46f9-a342-4cc6-a726-2f1581a5d481?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

The Newsletters plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 4.9.9.2. This is due to the plugin not restricting what user meta can be updated as screen options. This makes it possible for authenticated attackers, with subscriber-level access and above, to escalate their privileges to that of an administrator. Please note that this only affects users with access to edit/update screen options, which means an administrator would need to grant lower privilege users with access to the Sent & Draft Emails page of the plugin in order for this to be exploited. • https://plugins.trac.wordpress.org/browser/newsletters-lite/tags/4.9.9.1/wp-mailinglist.php#L3279 https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3146287%40newsletters-lite&new=3146287%40newsletters-lite&sfp_email=&sfph_mail= https://www.wordfence.com/threat-intel/vulnerabilities/id/2577102f-6355-4483-bd3d-1948497cb843?source=cve • CWE-269: Improper Privilege Management •

The Newsletters plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 4.9.9. This is due the plugin not preventing direct access to the /vendor/mobiledetect/mobiledetectlib/export/exportToJSON.php. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website. • https://plugins.trac.wordpress.org/browser/newsletters-lite/trunk/vendor/mobiledetect/mobiledetectlib/export/exportToJSON.php https://plugins.trac.wordpress.org/changeset/3135786 https://www.wordfence.com/threat-intel/vulnerabilities/id/3cbf52b0-4c7f-40fb-aedb-4c70f6510b1b?source=cve • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
