CVE-2026-14936

A vulnerability in the Simple Membership WordPress plugin prior to version 4.7.7 allows unauthorized individuals to initiate or prolong memberships by exploiting a flaw related to PayPal transaction verification.

This oversight enables malicious users to manipulate membership status using external payment sources.
