What is CVE-2026-93511?

The Premium Packages plugin for WordPress prior to version 7.2.1 contains a flaw that fails to verify PayPal's webhook signature before processing payment and subscription notifications. This vulnerability allows attackers to impersonate legitimate payment confirmations and subscription cancellations by forging notifications for any order, provided they possess the transaction ID. Consequently, this can lead to unauthorized financial transactions and subscription changes, posing a significant risk to users and merchants relying on this payment mechanism.

Affected Version(s)

Premium Packages 7.0.0 < 7.2.1
