Please note that your participation in the Bug Bounty Program is voluntary and subject to the terms and conditions set forth on this page (“Program Terms”). By submitting a site or product vulnerability to PayPal, Inc. (“PayPal”) you acknowledge that you have read and agreed to these Program Terms.

These Program Terms supplement the terms of PayPal User Agreement, the PayPal Acceptable Use Policy, and any other agreement in which you have entered with PayPal (collectively “PayPal Agreements”). The terms of those PayPal Agreements will apply to your use of, and participation in, the Bug Bounty Program as if fully set forth herein. If any inconsistency exists between the terms of the PayPal Agreements and these Program Terms, these Program Terms will control, but only with regard to the Bug Bounty Program.

PayPal will make a best effort to adhere to the following response targets:

Type of Response | Business days
---|---
First Response | 2 days
Time to Triage | 2 days
Time to Bounty | 14 days
Time to Resolution | depends on severity and complexity

Bounty Payments

Bounty Payments will be processed by PayPal rather than HackerOne at this

time. All Bounty Payments must be made to a verified PayPal Account in good standing. If you do not have a verified PayPal Account in good standing at the time of payment, you will not be eligible to receive a bounty

Exceptions will only be made in extraordinary circumstances agreed to by PayPal, in its sole discretion, via email from the Bug Bounty Program team). In order to receive payment, you'll be asked to add and verify your HackerOne email alias to you PayPal account.

You may be eligible to receive a monetary reward (“Bounty Payment”) if: (i) you are the first person to submit a site or product vulnerability; (ii) that vulnerability is determined to by a valid security issue by PayPal’s security team; and (iii) you have complied with all Program Terms.
Bounty Payments, if any, will be determined by PayPal, in PayPal’s sole discretion. In no event shall PayPal be obligated to pay you a bounty for any Submission. All Bounty Payments shall be considered gratuitous.

All Bounty Payments will be made in United States dollars (USD). You will be responsible for any tax implications related to Bounty Payments you receive, as determined by the laws of your jurisdiction of residence or citizenship.

PayPal will determine all Bounty Payments based on the risk and impact of the vulnerability. The minimum bounty amount for a validated bug submission is $50 USD and the maximum bounty for a validated bug submission is $30,000 USD.

PayPal Bug Bounty Team retains the right to determine if the bug submitted to the Bug Bounty Program is eligible. All determinations as to the amount of a bounty made by the PayPal Bug Bounty Team are final. Bounty Payment ranges are based on the classification and sensitivity of the data impacted, ease of exploit and overall risk to PayPal customers, PayPal brand and determined to be a valid security issue by PayPal’s security engineers.
