What is CVE-2026-115225?
The Customer Engagement System plugin for WordPress prior to version 2.0.2 contains a significant access control vulnerability. This flaw allows unauthenticated users to access its MailChimp interest-group functionality. Furthermore, the plugin fails to validate the supplied API key, enabling these users to initiate connections to arbitrary internal hosts and ports. By exploiting this vulnerability, attackers can infer the reachability of internal resources based on response timing, which poses a risk to the confidentiality and integrity of the system.
Affected Version(s)
Customer Engagement System 0 < 2.0.2
Exploit Proof of Concept (PoC)
