Ibotta

Description

Ibotta is a performance marketing platform based in Denver, CO, allows brands to deliver digital promotions to over 200 million consumers through the Ibotta Performance Network (IPN). The platform focuses on making every purchase rewarding and has credited American consumers $1.8 billion. Ibotta has been recognized as a Top Workplace by The Denver Post, BuiltIn Colorado's Best Places to Work list, and Inc.'s Best Workplaces list. No technology is perfect, and Ibotta believes that working with skilled security researchers across the globe is crucial in identifying weaknesses in any technology. We are excited for you to participate as a security researcher to help us identify vulnerabilities in our target. Good luck, and happy hunting! Ratings/Rewards: 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. All domains/properties owned by Ibotta are in scope! Ibotta continuously pushes out new code. Please take care when testing on production not to compromise the functioning of any Ibotta assets or users on the platform. Recent Scope Additions We highly recommend you take a look at this additional attack surface – which hopefully means more vulnerabilities! Name │ URL │ Description Chrome Extension Beta │ Access Here │ Here is a User Guide The Ibotta team is looking for testing that ensures the pop-up interaction with their other product areas (such as the next item or loyalty card linking) is secure and would like to know about any sensitive data exposure. Web v2 │ Access Here │ This is a refreshed web application for the Ibotta Team. Please note that there are some scope exclusions for this target: Access Token Exposure, the ability to scrape the site, and data flow to 3rd parties is intended and reports will be considered informational unless they are chained to create a larger vulnerability. All vulnerability reports must be submitted exclusively through the Bugcrowd platform. Attempts to contact Ibotta security or care teams directly regarding vulnerability reports will not be addressed.

Targets

Access Researchers can self register for an account using your @bugcrowdninja.com email address. For more info regarding @bugcrowdninja email addresses, see here . Researchers will need to have a rewards account on any of these grocery chains . These will not be provisioned by Bugcrowd or Ibotta. Geo Restrictions Ibotta is currently for US use only. International researchers are welcome to test against Ibotta assets but must do so through a US IP address (through a self provisioned proxy/vpn). Helpful Information Account Flow The below documentation contains information regarding how to initiate and use the flow of the application, and API endpoint data and examples. We also have included a video on how to initiate and use the flow. Documentation 1: Pay with Ibotta Flow.docx Documentation 2: Ibotta - Account Linking Flow.docx Video: Can be downloaded from the Resources tab Chrome Extension Here is a User Guide The Ibotta team is looking for testing that ensures the pop-up interaction with their other product areas (such as the next item or loyalty card linking) is secure and would like to know about any sensitive data exposure. Cash out A key use case for the Ibotta application is cashing out. For testing cash out in this program please be aware of the following: Paypal, Venmo, and giftcard cashout methods are live. Because of this, accounts will not be funded again. Cashout thresholds are reduced for the bugcrowd provisioned accounts to facilitate testing. SMS authentication is enabled for all accounts. Because of fraud scoring, VoIP numbers (Google Voice, etc) may be blocked. Critical requests are rate-limited and geoip filtered. Requests from outside the US are not likely to be allowed. Technology The mobile apps are both native Servers are Ruby/Rails on Ubuntu Hosted on AWS, API endpoints behind Elastic LoadBalancer Infrastructure includes Memcache, Redis and MySQL Focus Areas Any ability for an attacker to sniff Grocery retailers credentials entered into Ibotta. All phone logs, especially exceptions, need to be verified to not include credentials. Check for plaintext customer sensitive information sent to 3rd party from our endpoints. Input validation for database access for protection against injection. Test the restriction of HTTP methods to those we are in control of, or any attack vector against our endpoints. 2FA bypass and/or compromising account integrity. Cashout threshold and value manipulation. N-day/Third-Party 0-day Policy When N-day or third-party 0-day vulnerabilities are released publicly, we will consider them in scope after a grace period of 7 days has elapsed. Example: If an N-day vulnerability is released on 01/01/2025, it would be considered in-scope starting 01/08/2025. Bounty reports submitted on vulnerabilities that were made public less than 7 days ago will be paid at the sole discretion of Ibotta. We ask that you only test on Ibotta owned assets and are respectful of our customers. All testing must abide by AWS's rules on penetration testing . Out-of-Scope Testing of third-party services used by Ibotta, except where explicitly permitted as 'In Scope' investors.ibotta.com, ir.ibotta.com & trust.ibotta.com are hosted by third parties and are * out of scope * No attacks/tests of any kind should be performed on the Grocery websites/properties Creating counterfeit receipts and barcodes Double submission of receipts Other customer-support situations Denial of Service via high rate requests or other nonstandard requests Rate limiting on endpoints Subdomain takeovers Dmarc/Email spoofing Lack of source code obfuscation (ios-class-guard, ProGuard) for mobile apps Regarding Webv2; Access Token Exposure, the ability to scrape the site, and data flow to 3rd parties is intended and reports will be considered informational unless they are chained to create a larger vulnerability Regarding the mobile App; Access Token/Public Key Exposure, and data flow to 3rd parties is intended and reports will be considered informational unless they are chained to create a larger vulnerability Rating Taxonomy This program adheres to the Bugcrowd Vulnerability Rating Taxonomy for the prioritization of findings. Safe Harbor: When conducting vulnerability research according to this policy, we consider this research to be: Authorized in accordance with the Computer Fraud and Abuse Act (CFAA) (and/or similar state laws), and we will not initiate or support legal action against you for accidental, good faith violations of this policy; Exempt from the Digital Millennium Copyright Act (DMCA), and we will not bring a claim against you for circumvention of technology controls; Exempt from restrictions in our Terms & Conditions that would interfere with conducting security research, and we waive those restrictions on a limited basis for work done under this policy; and Lawful, helpful to the overall security of the Internet, and conducted in good faith. You are expected, as always, to comply with all applicable laws.

Additional information

Important: Contacting Ibotta's support team directly to inquire about the status or examination of a BugCrowd submission ("Submission") will result in an immediate disqualification from receiving rewards. ALL communications must be conducted through the CrowdControl platform only. Public Zero-Day vulnerabilities that have had an official patch for less than 1 month will be awarded on a case-by-case basis.

In Scope Targets (in scope)

The web APIs are updated daily, and the mobile app is updated bi-weekly. In the event you don't find anything today, there may be something present tomorrow and as such, vulnerability reports on these targets are of the highest impact to the Ibotta team and have a higher reward range! The Chrome extension was recently moved out of Beta so we are particularly interested in testing that ensures the pop-up interaction with their other product areas (such as the next item or loyalty card linking) is secure and would like to know about any sensitive data exposure.
