## Summary

The Sadad QA Payment plugin for WordPress, used to accept online payments, is affected. An unauthenticated attacker can forge payment confirmations and mark orders as paid without actually paying.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Sadad QA Payment: 1.28 only

## Description

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.
