Western Union is a financial services and communications company based in the United States.
For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.
Regarding scope: If you are unsure if something is related to Western Union, please let us know anyway! While you will not receive kudos points for items we don't expressly own and manage, you will not be penalized via negative kudos points.
Any western union web or device property that is out of scope for our Cash based Program here, will be taken into consideration in this program.
