What is CVE-2026-15240?

The Customer Switching plugin for WordPress prior to version 2.1.3 has a security flaw that allows a user with lower privileges to exploit an active session. When an operator switches to another user account, the session is not securely bound, enabling the lower-privileged user to perform actions as the operator—potentially leading to unauthorized access to higher-privileged accounts, including full administrator rights.

Affected Version(s)

Customer Switching 0 < 2.1.3

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.
