Email Subscribers Newsletters Email Marketing Post Notifications Newsletter Plugin For Wordpress
Monthly
Arbitrary shortcode execution in the Icegram Email Subscribers & Newsletters WordPress plugin (all versions through 5.9.27) allows unauthenticated network attackers to invoke registered WordPress shortcodes without authentication. The flaw originates in the plugin's email workflow and subscription handling code, which passes user-controlled input to `do_shortcode()` without adequate validation - enabling attackers to trigger any shortcode registered on the target site. Depending on the shortcodes available, impact ranges from information disclosure and content manipulation to potential code execution; no public exploit or CISA KEV listing has been identified at time of analysis.
