The Email Subscribers & Newsletters plugin for WordPress versions up to and including 5.9.27 contains a vulnerability that allows unauthenticated attackers to execute arbitrary shortcodes. This occurs because the plugin does not properly validate input before passing it to the do_shortcode function, leading to improper control of code generation (CWE-94). The vulnerability has a medium severity rating with a CVSS score of 6.5.
The Icegram Mailer plugin for WordPress is vulnerable to SQL Injection via the 'fields' parameter in versions up to, and including, 1.0.12. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the Icegram_Mailer_Logs_Table::get_logs() function, where each element of the `fields` array received from $_REQUEST['data'] is joined verbatim into the SELECT clause via implode() with no whitelist, escaping, or prepared-statement placeholder. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Icegram Engage – Popups, Optins, CTAs & Lead Generation plugin for WordPress is vulnerable to second-order SQL Injection via 'messages[][id]' Parameter in all versions up to, and including, 3.1.42 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 contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection is second-order: the malicious id value is first persisted to post meta via the save_campaign_preview() AJAX action (gated by a nonce check and edit_post capability, requiring Editor-level access or above), and only executed as SQL when a subsequent preview request triggers get_message_data() to interpolate the stored value directly into a SQL IN() clause without $wpdb->prepare() or integer casting.
The Email Subscribers & Newsletters – Email Marketing, Post Notifications & Newsletter Plugin for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.9.27. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to overwrite plugin mail settings (from name and from email address), create audience lists, insert arbitrary contacts into those lists, create and overwrite newsletter broadcasts and post notifications, add workflows, and queue and dispatch mass email to arbitrary recipients.
The Email Subscribers by Icegram Express plugin for WordPress is vulnerable to SQL Injection via the 'workflow_ids' parameter in all versions up to, and including, 5.9.16 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.

The Icegram Express - Email Subscribers, Newsletters and Marketing Automation Plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 5.9.10. This is due to the plugin not properly verifying that a user is authorized to perform an action in the `run_action_scheduler_task` function. This makes it possible for unauthenticated attackers to execute scheduled actions early or repeatedly by guessing action IDs, potentially triggering email sends, maintenance tasks, or other privileged operations, causing unexpected state changes and resource usage.
