CVE-2026-103330
Sadad QA Payment 1.28 - Unauthenticated Arbitrary Order Payment Confirmation via Signature Bypass
CVSS Score
5.3
EPSS Score
0.0%
EPSS Percentile
0th
The Sadad QA Payment WordPress plugin through 1.28 does not correctly verify the authenticity of incoming payment notifications, as the verification is keyed on a merchant secret that is empty by default and the rest of the signed data is attacker-controlled, allowing unauthenticated attackers to forge a valid confirmation and mark orders as paid without payment.
