What is CVE-2026-90922?

A flaw in the Paid Membership Subscriptions WordPress plugin prior to version 3.0.9 allows unauthenticated users to gain access to paid memberships by completing payments with amounts that do not match the expected payment criteria. This occurs because the plugin fails to verify the accuracy of amounts and currency reported by the payment provider before finalizing the transaction, enabling unauthorized access to premium content.

Affected Version(s)

Paid Membership Subscriptions 0 < 3.0.9

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.
