What is CVE-2026-15931?
The Simple Membership plugin for WordPress allows unauthenticated users to send a malicious payment approval request, which includes an unsanitized subscriber name. This leads to the potential execution of arbitrary JavaScript in an administrator's session. Because the plugin doesn't properly escape the subscriber name when displaying it in the admin dashboard, it exposes the site to Cross-Site Scripting (XSS) attacks, heightening the risk of unauthorized actions taken by attackers during an administrator's session.
Affected Version(s)
Simple Membership 0 < 4.7.8
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
